Mock Test On Chemical Kinetics

INTRODUCTION:-Three impotant characteristics of chemical reactions include : extent of reaction, feasibility and its rate. In standard XI, we learnt how equilibrium constants predict the extent of reaction. In unit 3 of this text, we learnt how thermodynamics properties such as change in entropy or enthalpy tell us whether under the given set of conditions chemical equation occurs or not. chemical kinetics is a branch of chemistry reactions and the factors those affect them.

A chemist wants to know the rates of reactions for different reasons rates help us to predict how rapidly the reaction approaches equilibrium. Secondly it gives information on the mechanism of chemical reactions.

A number of reactions occurs as a sequence of elementary steps constitution the mechanism of reaction.
