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)`, 104.4 kJ `mol^(-1)` and `6.0 x 10^(14)s^(-1)` respectively. The value of rate constant at T `rarr infty` is

Options

A. `2.0xx10^(18)s^(-1)`
B. `6.0xx10^(14)s^(-1)`
C. infinity
D. `3.6xx10^(30)s^(-1)`

Answer

B

Explanation

`k=3.0xx10^(-4)s^(-1),E_a`=104.4 kJ`//`mol
`A=6.0xx10^(14)s^(-1),k=Ae^(-E_a//RT)`
As T `rarr infty,k=Ae^(0)`=A=6.0`xx10^(14)s^(-1)`
