What is chemical kinetics? Which information is obtained by chemical kinetics and thermodynamics regarding a reaction?
(N/A) Chemical kinetics is the branch of chemistry that deals with the study of reaction rates and their mechanisms. The term is derived from the Greek word 'kinesis' meaning movement.
Information obtained from chemical kinetics:
$(i)$ The rate of reaction.
$(ii)$ Factors affecting the rate of reaction.
$(iii)$ The mechanism by which the reaction proceeds.
Information obtained from thermodynamics:
$(i)$ It determines whether a reaction is feasible or not (spontaneity).
$(ii)$ It provides information about the equilibrium state of the reaction.
$(iii)$ It does not provide information about the rate of the reaction.
