The rate constant `(K')` of one reaction is double of the rate constant (K") of another reaction. Then the relationship between the corresponding activation energies of the two reactions `(E_(a)^(') "and" E_(a)^(''))` will be

A

`E_a^' gt e_a^''`

B

`E_a' lt E_a''`

C

`e_a'=E_a''`

D

`E_a'= 4 E_a''`

Text Solution
