NCERT Exemplar Class 11 Chemistry Chapter 7 - Equilibrium - Free PDF Download

NCERT Exemplar Chapter 7 – Equilibrium contains approximately 76 questions across six sections: single-correct MCQs, multiple-correct MCQs, two levels of short answers, long answers, and matching/assertion-reason type questions. Each section targets a different level of conceptual depth, from recall to application to analysis.

NCERT Exemplar Chapter 7 is a strong foundation but not sufficient on its own for JEE Main. It covers all core concepts thoroughly, but JEE Main Equilibrium questions — especially numerical answer type (NAT) — require additional problem sets. Pair Exemplar with previous year JEE Main questions from 2019 to 2025 for complete preparation.

Le Chatelier's Principle, pH calculations of weak acids and bases, and the common ion effect are the most frequently tested Equilibrium topics in NEET. Buffer solutions and Ksp-based problems also appear regularly. Students should prioritise these areas while practising from the Exemplar.

Kc is the equilibrium constant expressed in terms of molar concentrations, while Kp is expressed in terms of partial pressures of gaseous species. The relationship between them is Kp = Kc × (RT)^Δn, where Δn is the change in moles of gas (moles of gaseous products minus moles of gaseous reactants), R is the gas constant, and T is temperature in Kelvin.
