Q 1244334253.     Activation energy and pre-exponential factor of a chemical reaction are `2 × 10^2` `kJ ` `mol^(-1)` and `3 × 10^15 s^(-1)` respectively. If the rate constant of the reaction at `298`K is `5.0 × 10^(-1)` , its value when `T → ∞` is:

A

`2.2 × 10^2 s^-1`

B

`1.7 × 10^11s^-1`

C

`3.0 × 10^15 s^-1`

D

`2.5 × 10^5s^-1`

HINT
