Chemistry - Chemical Equilibrium

Practise 21 MHTCET previous year questions on Chemical Equilibrium, compiled from papers spanning 2016 to 2026. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty MHTCET tests.

Chemical Equilibrium has been asked in 6 of the 17 years of MHTCET papers analysed (2007–2026), with 21 questions in all. 29% of them were easy, 67% moderate and 5% tough. Most of its questions came from 2021, with 9 questions that year. In the last three years (2024–2026) it had 3 questions across 59 papers, about 0.1 per paper.

The chapter's 2 topics are not weighted equally: Law of Mass Action, Equilibrium Constant (Kc and Kp) and its Application (20 questions, 95%) and Le chatelier's principle (1 question, 5%) 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 10 questions. Law of Mass Action, Equilibrium Constant (Kc and Kp) and its Application has produced the most tough questions (1).
