Chemical Thermodynamics Weightage for JEE

106+ syllabus-aligned questions available

Quick answer

Chemical Thermodynamics appears regularly in JEE Main and Advanced. Focus on high-frequency subtopics from Fundamentals of thermodynamics: System and surroundings, extensive and intensive properties, state functions, entropy, types of processes, The first law of thermodynamics: Concept of work, heat, internal energy and enthalpy, heat capacity, molar heat capacity, Hess's law of constant heat summation, Enthalpies of bond dissociation, combustion, formation, atomization, sublimation, phase transition, hydration, ionization and solution, and more and pair revision with timed MCQs.

Prioritise high-return topics first. This weightage guide for Chemical Thermodynamics helps you allocate revision time before JEE Chemistry papers.
