The pre-exponential factor for the free radical addition of chloring is `2xx10^(13)s^(-1)`. Find the rate constant of this reaction at `STP`.

Explanation

To find the rate constant (k) for the free radical addition of chlorine at standard temperature and pressure (STP), we can use the Arrhenius equation:

\[ k = A e^{-\frac{E_a}{RT}} \]

Where:
- \( k \) = rate constant
- \( A \) = pre-exponential factor
- \( E_a \) = activation energy
