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

Options

A. `2.0 xx 10^(18) "s"^(-1)`
B. `6.0 xx 10^(14) "s"^(-1)`
C. `oo`
D. `3.6 xx 10^(30) "s"^(-1)`

Answer

B

Explanation

`K = A xx e^(-"ExRT") = A xx e^(-"ExRT") = A = 6.0 xx 10^(11) "s"^(-1)`
