The time required for 10% completion of a first order reaction at 298 K is equal to that required for its 25% completion at 308 K. If the pre-exponential factor for the reaction is `3.56 xx10^9s^(-1)`, calculate its rate constant at 318 K.

Options

A. `0.92xx10^(-4)s^(-1)`
B. `9.22xx10^(-4)s^(-1)`
C. `92.2xx10^(-4)s^(-1)`
D. `92xx10^(-4)s^(-1)`

Answer

B
