NCERT Class 11 Chemistry Chapter 6 Equilibrium Test Mock Test
This free online test covers Chapter 6, Equilibrium, from the NCERT Class 11 Chemistry Part I textbook. The 30 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions
Q1.Why is it not possible to reach equilibrium when 1 mL of acetone is left in an open watch glass in a room?
- AAcetone molecules are destroyed as soon as they enter the vapour phase
- BThe rate of evaporation falls steadily until it becomes zero
- CThe temperature of the liquid rises continuously as it evaporates
- DThe vapour disperses into the large volume of the room, so the rate of condensation stays far below the rate of evaporation
Q2.For a pure liquid, the temperature at which the liquid and its vapour are in equilibrium at one atmospheric pressure of 1.013 bar is called its:
- ACritical temperature
- BNormal freezing point
- CSublimation point
- DNormal boiling point
Q3.Haber's experiment in which ammonia synthesis was carried out with deuterium in place of dihydrogen, and the two equilibrium mixtures were then mixed, showed that:
- AIsotopes cannot be used to study chemical equilibria
- BDeuterium reacts with nitrogen faster than hydrogen does, giving a different equilibrium composition
- CForward and reverse reactions continue at equilibrium, since all deuterated forms of ammonia and dihydrogen appear on analysis
- DThe reaction stops completely once equilibrium has been reached
