Thermodynamics — NEET/JEE Questions, Notes & Weightage
Class 11 Thermodynamics & Equilibrium NEET weightage: High 178 questions
Covers the first law of thermodynamics, enthalpy, Hess's law, entropy, Gibbs free energy, and spontaneity. Enthalpy-of-reaction numericals (using Hess's law or bond enthalpies) and Gibbs-free-energy spontaneity questions recur almost every year.

Frequently asked questions
What is the single most-tested formula here?
ΔG = ΔH − TΔS, used to predict reaction spontaneity at given temperatures, is the chapter's most frequently applied formula in NEET/JEE numericals.
Is Hess's law tested as direct numericals?
Yes — combining multiple given reactions and their enthalpies to find an unknown reaction enthalpy is a standard, recurring question format.
