The rate constant, the activation energy...

The rate constant, the activation energy, and the Arrhenius parameter of a chemical reaction at `25^(@)C` are `3.0xx10^(-4)S^(-1), 104.4 KJ mol^(-1)`, and `6.0xx10^(14)S^(-1)`, respectively. The value of the rate constant as `Trarroo` is

A

`2.0xx10^(8)s^(-1)`

B

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

C

`oo`

D

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

Text Solution

Verified by Experts

The correct Answer is:
B

`k = Ae^(-E_(a)//RT)`
When `t rarr oo`
`k rarr A`
`A = 6 xx 10^(14)s^(-1)`
