Chemistry - Chemical Kinetics

Practise 99 AP EAMCET previous year questions on Chemical Kinetics, compiled from papers spanning 2001 to 2025. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty AP EAMCET tests.

Chemical Kinetics has been asked in 22 of the 24 years of AP EAMCET papers analysed (2001–2024), with 99 questions in all. 38% of them were easy, 51% moderate and 11% tough. Most of its questions came from 2021, with 13 questions that year. In the last three years (2022–2024) it had 29 questions across 28 papers, about 1 per paper.

The chapter's 5 topics are not weighted equally: Integrated rate laws (30 questions, 30%), Rate law and rate constant (23 questions, 23%), and Arrhenius theory (21 questions, 21%) have been asked the most. Integrated rate laws has also led over the last five years, with 17 questions. Integrated rate laws has produced the most tough questions (4).
