For a first order reaction $A \rightarrow P$,the temperature $(T)$ dependent rate constant $(k)$ was found to follow the equation $\log k = -(2000) \frac{1}{T} + 6.0$. The pre-exponential factor $A$ and the activation energy $E_{a}$,respectively,are
- A$1.0 \times 10^6 \ s^{-1}$ and $9.2 \ kJ \ mol^{-1}$
- B$6.0 \ s^{-1}$ and $16.6 \ kJ \ mol^{-1}$
- C$1.0 \times 10^6 \ s^{-1}$ and $16.6 \ kJ \ mol^{-1}$
- D$1.0 \times 10^6 \ s^{-1}$ and $38.3 \ kJ \ mol^{-1}$
