The rate constant, the activation energy...

The rate constant, the activation energy and the Arrhenius parameter of a chemical reactions at `25^(@)C` are `3.0xx10^(-4)s^(-), "104.4 kJ mol"^(-1)` and `6xx10^(14)s^(-1)` respectively. The value of the rate constant as `T rarr oo` is

A

`2.0 xx 10^(18)s^(-1)`

B

`6.0 xx 10^(14)s^(-1)`

C

Infinity

D

`3.6 xx 10^(30)s^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`K=Ae^(-Ea//RT)`, when `T to infty`, then K=A
