The activation energies of two reactions...

The activation energies of two reactions are `E_1` and `E_2 (E_1 > E_2)`. If the temperature of the system is increased from `T_1` to `T_2` the rate constant of the reaction changes from `k_1` to `k_1'` in the first reaction and `k_2` to `k_2'` in second reaction, predict which of the following expression is correct ?

A

`(k_1')/k_1 = (k_2') /k_2`

B

`(k_1')/k_1 gt(k_2') /k_2`

C

`(k_1')/k_1lt(k_2') /k_2`

D

`(k_1')/k_1 = (k_2') /k_2=0`
