Problem

The time required for 10% completion of a first order reaction at

298 \text{ K}

is equal to that required for its 25% completion at

308 \text{ K}

. If the pre-exponential factor for the reaction is

3.56 \times 10^9 \text{ s}^{-1}

, calculate its rate constant at

318 \text{ K}

and also the energy of activation.
