Chemistry - Chemical Kinetics
Practise 24 Manipal (MET) previous year questions on Chemical Kinetics, compiled from papers spanning 2010 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 Manipal (MET) tests.
Chemical Kinetics has been asked in 14 of the 15 years of Manipal (MET) papers analysed (2010–2024), with 24 questions in all. 54% of them were easy, 33% moderate and 13% tough. Most of its questions came from 2015, with 3 questions that year. In the last three years (2022–2024) it had 2 questions across 2 papers, about 1 per paper.
The chapter's 4 topics are not weighted equally: Arrhenius theory (7 questions, 29%), Rate law and rate constant (7 questions, 29%), and Integrated rate laws (5 questions, 21%) have been asked the most. Over the last five years the most frequent topics have been Rate of reaction (2), Arrhenius theory (1), and Integrated rate laws (1). Rate law and rate constant has produced the most tough questions (2).
