If your search is to get the 1st Year Chemistry Chapter 8 Reaction Kinetics MCQs with Answers then you are on the right site. This chapter is about the rates of chemical reactions and the factors that affect the rates of a chemical reaction. Chemical Reactions are of three types i.e. Very fast reaction, very slow reaction, and moderately slow reaction. Then there is the concept of the rate of the reaction which is the change in concentration of the substance divided by the time taken for the change. An important concept is the Energy of Activation, catalysts, and determination of the Rate of Reaction. So, here below, you can check the important Multiple Choice Questions that are important for the Entrance Test. Solve the quiz given below that will help you prepare for the entry test.
