For a first order reaction (A → B). the temperature (T) dependent rate constant (k) in \sec^{-1} was found to follow the equation: log k =(-20/T)+4. The activation energy (E_a) and pre-exponential factor (A) respectively, are

Correct Answer is : 92.12 cal mol−1 and 104s−1

46.06 cal mol^{-1} and 10^{-4}\s^{-1}

92.12 cal mol^{-1} and 10^{4}\s^{-1}

46.06 cal mol^{-1} and 10^{4}\s^{-1}

9.212 cal mol^{-1} and 10^{-4}\s^{-1}
