# Order of Reaction Can be Zero

The order of reaction is the sum of all exponents of the concentration terms. The order of reaction is directly proportional to the concentration of reactant but in somecases it can be zero.It is observed when the rate of reaction is independent of the concentration of this reactant.

Here Example of such reaction

$$(CH_{3})_{3}C-CL$$+$$OH^{-1}$$$$\large{→}$$$$(CH_{3})_{3}$$$$-OH$$+$$CL^{-1}$$,

the rate does not depend on concentration of $$OH^{-1}$$ while with respect to $$(CH_{3})_{3}$$ the order is one. So,overall order of reaction is one despite of two reactants.

In reactions involving water as one of the two reactants,the order w.r.to $$H_{2}O$$ is usually Zero as the concentration of the water changes negligibly during the course of reaction $$i.e.$$ the rate is independent of the concentration of water.
