Chemistry - Chemical Equilibrium

Practise 14 BITSAT previous year questions on Chemical Equilibrium, compiled from papers spanning 2009 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty BITSAT tests.

Chemical Equilibrium has been asked in 11 of the 16 years of BITSAT papers analysed (2009–2024), with 14 questions in all. 50% of them were easy, 43% moderate and 7% tough. Most of its questions came from 2024, with 2 questions that year. In the last three years (2022–2024) it had 3 questions across 3 papers, about 1 per paper.

The chapter's 2 topics are not weighted equally: Law of Mass Action, Equilibrium Constant (Kc and Kp) and its Application (11 questions, 79%) and Le chatelier's principle (3 questions, 21%) have been asked the most. Law of Mass Action, Equilibrium Constant (Kc and Kp) and its Application has also led over the last five years, with 4 questions. Le chatelier's principle has produced the most tough questions (1).
