The rate constant, the activation energy...

The rate constant, the activation energy and the Arrhenius parameter of a chemical reaction at `25^(@)C` are `3.0 xx 10^(-4) s^(-1), 104 "kJ mol"^(-1)` and `6.0 xx 10^(14)s^(-1)` respectively. The value of the rate constant as `T rarr oo` is

A

`2.0xx10^(18) s^(-1)`

B

`6.0xx10^(14) s^(-1)`

C

Infinity

D

`3.6xx10^(30) s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
For `T rarrooe^(-E_(a)//RT)rarr1`
Hence `k rarr A," "k=6.0xx10^(14)s^(-1)`
