Topics in Chemical Thermodynamics
Every topic of Chemical Thermodynamics, ordered by how many published questions sit behind it. A topic with none is listed rather than hidden — it is part of the chapter either way.
- First law; internal energy, work and heat
- System, surroundings, state functions and properties
- Enthalpy, heat capacity and their measurement
- Hess's law of constant heat summation
- Standard enthalpy changes
- Spontaneity; entropy and the second law
- Gibbs energy, spontaneity and the equilibrium constant
- Third law of thermodynamics
Chemical Thermodynamics weightage in NEET-UG 2026 and JEE Main 2026
These shares are measured across many years of past papers, so they describe the long run rather than predicting any single paper.
| Paper | Share of Chemistry | Typical questions | Typical marks |
|---|---|---|---|
| NEET-UG 2026 chapter-wise weightage | 5.2% | 2.3 | 9.4 |
| JEE Main 2026 chapter-wise weightage | 5.2% | 1.3 | 5.2 |
Previous year questions from Chemical Thermodynamics
Past-paper questions are the most trustworthy material in the bank, and assembly reaches for them first when it builds a Chemical Thermodynamics test. They are not listed separately here, because a question's value is that you meet it under a clock rather than that you read it in a list.
A Chemical Thermodynamics test draws from all 268 published questions in this chapter, past papers first. Sit one now and see the per-topic breakdown.
