For a reaction, `E_(a)= 0 and k= 3.2xx10^(4)s^(-1)` at `300 K`. The value of `k` at `310 K` would be

A

`6.4 xx 10^(4) s^(-1)`

B

`3.2 xx 10^(4) s^(-1)`

C

`3.2 xx 10^(8) s^(-1)`

D

`3.2 xx 10^(5) s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`k = Ae^(-E_(a)//RT)`
When `E_(a) = 0, k = A =` constant
`:. k_(310) = k_(300) = 3.2 xx 10^(4) s^(-1)`.
