Chemistry - Chemical Equilibrium

Practise 27 VITEEE previous year questions on Chemical Equilibrium, compiled from papers spanning 2006 to 2023. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty VITEEE tests.

Chemical Equilibrium has been asked in 15 of the 18 years of VITEEE papers analysed (2006–2024), with 27 questions in all. 52% of them were easy, 48% moderate and 0% tough. Most of its questions came from 2018, with 3 questions that year. In the last three years (2022–2024) it had 3 questions across 2 papers, about 1.5 per paper.

The chapter's 2 topics are not weighted equally: Law of Mass Action, Equilibrium Constant (Kc and Kp) and its Application (15 questions, 56%) and Le chatelier's principle (12 questions, 44%) have been asked the most. Over the last five years the most frequent topics have been Le chatelier's principle (3) and Law of Mass Action, Equilibrium Constant (Kc and Kp) and its Application (1).
