The values of rate constants of some reactions are given below . Determine the order in each case.
`k=6.2xx10^(-3)s^(-1)`

Text Solution

Verified by Experts

For the given reaction , rate constant `(k)=6.2xx10^(-3)s^(-1)=6.2xx10^(-3)("mol.L"^(-1)).s^(-1)` . If the order of the reaction = n , then the unit of `k=("mol.L"^(-1))^(1-n).s^(-1)` . By comparison , we have , 1 - n = 0 or , n = 1 So , order of the reaction = 1 .
