Question

Write four differences between rate of reaction and constant.

Answer 1

Differences between rate of reaction and constant:

	Rate of Reaction	Rate Constant
(i)	It depends upon concentration of reactant	It is independent of concentration of reactant.
(ii)	It is expressed in terms of consumption of reactants or formation of product per unit time.	It is proportionality constant in differential form in rate law or rate equation.
(iii)	It generally decreases with the progress of reaction	It does not depend on the progress of reaction
(iv)	Its unit is mol $L^{-1}c{m}^{-1}$.	It changes according to order of reaction.
