Physical chemistry help is one-to-one support from a chemistry tutor who explains the physics and maths behind chemical behaviour, and helps you solve numerical problems, derive equations and write lab reports.
| What you need | Best option | What you get |
|---|---|---|
| Regular lessons through a physical chemistry module | Live one-to-one tutoring | Concepts and equations explained |
| Problems you are stuck on | Homework help | Step-by-step worked solutions |
| A graded lab report | Assignment help and lab report help | Guidance within your rules |
This map lists the core physical chemistry topics, the point where students most often get stuck, and how a tutor helps you past it.
| Topic | Where students get stuck | How a tutor helps |
|---|---|---|
| Gases | Ideal and real gas behaviour | Worked gas law problems |
| Thermodynamics | Enthalpy, entropy and the laws | Worked energy calculations |
| Gibbs energy | Spontaneity and equilibrium constants | Worked ΔG to K conversions |
| Equilibrium | Le Chatelier and Kc versus Kp | Worked ICE tables |
| Kinetics | Rate laws, orders and half-lives | Worked integrated rate laws |
| Arrhenius | Activation energy from rate data | Worked Ea calculations |
| Electrochemistry | Cell potentials and the Nernst equation | Worked cell problems |
| Quantum and spectroscopy | Energy levels and spectra | Worked spectroscopy examples |
Tutors cover school and university syllabi.
| Area | Topics |
|---|---|
| States of matter | Gas laws, kinetic theory, real gases, liquids, solids |
| Thermodynamics | First, second and third laws, enthalpy, entropy, Gibbs energy |
| Equilibrium | Equilibrium constants, phase equilibria, colligative properties |
| Kinetics | Rate laws, mechanisms, Arrhenius equation, catalysis |
| Electrochemistry | Cells, electrode potentials, Nernst equation, conductance |
| Quantum chemistry | Schrödinger equation, particle in a box, atomic and molecular orbitals |
| Spectroscopy and surfaces | UV-visible, IR and NMR principles, adsorption isotherms |
Two common calculations.
| Question | Working | Answer |
|---|---|---|
| First-order reaction with k = 0.0231 min⁻¹. Half-life? | t½ = 0.693 ÷ 0.0231 | 30 minutes |
| Fraction remaining after 90 minutes | 3 half-lives: (1/2)³ | 12.5% |
| A rate constant doubles from 300 K to 310 K. Activation energy? | ln 2 = (Ea ÷ R)(1/300 − 1/310); Ea = 0.693 × 8.314 ÷ 0.0001075 | ≈ 53.6 kJ/mol |
This is the origin of the rule of thumb that many reactions roughly double in rate for a 10 K rise near room temperature.
For N₂ + 3H₂ → 2NH₃ at 298 K, ΔH° = −92.2 kJ and ΔS° = −198.7 J/K.
| Question | Working | Answer |
|---|---|---|
| ΔG° at 298 K | −92.2 − 298 × (−0.1987) | ≈ −33.0 kJ |
| Equilibrium constant | K = e^(−ΔG° ÷ RT) = e^(32,990 ÷ (8.314 × 298)) | ≈ 6 × 10⁵ |
| Daniell cell: E° = 1.10 V, [Zn²⁺] = 1.0 M, [Cu²⁺] = 0.01 M. Cell potential? | E = 1.10 − (0.0592 ÷ 2) log(1.0 ÷ 0.01) | ≈ 1.04 V |
A negative ΔG° means the reaction is spontaneous under standard conditions; ΔS° is negative, so it becomes less favourable at high temperature.

Most lost marks come from unit and sign errors.
| Mark-loser | What to do instead |
|---|---|
| Mixing kJ and J | Convert ΔH to J before combining with TΔS in J/K |
| Celsius instead of kelvin | Always use kelvin in thermodynamics and kinetics |
| Wrong sign conventions | Check signs for heat, work and ΔG |
| Wrong rate law order | Determine order from data, not the equation |
| Log versus ln confusion | Use ln with R and log₁₀ with 0.0592 in the Nernst equation |
| Graphs without units | Label axes with quantities and units |
Physical chemistry is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Exams | Numerical problems, derivations and explanations |
| Problem sheets | Complete working with units |
| Lab reports | Data analysis with graphs and error discussion |
| Internal assessments | Well-designed kinetics or thermochemistry investigations |
| Vivas | Explaining experiments and equations |
Physical chemistry uses these tools.
| Tool | What it is used for |
|---|---|
| Excel or Origin | Graphing and fitting data |
| Spectrophotometers | Kinetics and concentration measurements |
| Calorimeters | Enthalpy measurements |
| Potentiometers and pH meters | Electrochemistry |
| Data booklets | Constants and standard values |
Physical chemistry is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where physical chemistry is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | A-Level Chemistry and BSc Chemistry | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | Harvard or a journal style |
| United States | AP Chemistry and college physical chemistry | Letter grades A–F and a 4.0 GPA scale | APA, CSE or ACS |
| Australia | Senior chemistry and university units | HD, D, C, P at university; ATAR for school leavers | Harvard or APA |
| Canada | High school and university chemistry | Letter grades or percentages; GPA scales vary by province and university | APA or CSE |
| India | CBSE/ICSE Class 11–12, JEE and NEET, BSc and MSc Chemistry | Board exam percentages; university CGPA, often on a 10-point scale | As your university specifies |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of physical chemistry help depends on the type of task and your deadline. A short numerical costs less than a full lab report. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Yes. Tutors explain concepts, derivations and numericals and help with lab reports, within your rules.
The branch of chemistry that uses physics and maths to explain chemical behaviour, energy and rates.
G = H − TS; a negative ΔG means a process is spontaneous at constant temperature and pressure.
ΔG° = −RT ln K.
Subtract the sum of standard entropies of reactants from that of products: ΔS° = ΣS°(products) − ΣS°(reactants).
The total enthalpy change of a reaction is the same whatever route it takes.
Use initial rates, integrated rate law plots or half-life behaviour.
t½ = 0.693 ÷ k, independent of starting concentration.
k = A e^(−Ea ÷ RT), linking the rate constant to activation energy and temperature.
E = E° − (RT ÷ nF) ln Q, giving the cell potential under non-standard conditions.
A system at equilibrium shifts to oppose a change in conditions.
Kc uses concentrations; Kp uses partial pressures. They are related by Kp = Kc(RT)^Δn.
A quantum model of a particle confined in a region, giving quantised energy levels.
Yes. Tutors cover the numerical topics in both syllabi.
It is maths-heavy; consistent units and worked examples help.
