Activation energy of any chemical reaction can be calculated if one knows the value of
probability of collision
orientation of reactant molecules during collision
rate constant at two different temperatures
rate constant at standard temperature
Solution
To calculate value of $E_a$
Equation used is
$\log \left(\frac{k_2}{k_1}\right)=\frac{E_a}{2.303 R}\left(\frac{1}{T_1}-\frac{1}{T_2}\right)$
Hence $E_a$ can be calculated if value of rate constant $k$ is known at two different temperatures $T_1$ and $\mathrm{T}_2$.
