Q. The Activation energy of a chemical reaction can be determined by

AIPMTAIPMT 1998Chemical Kinetics

Solution:

Activation energy $\left(E_{a}\right)$ can be determined by evaluating rate constants at two different temperatures using the following relation

$\log \frac{k_{2}}{k_{1}}=\frac{E_{a}}{2303 R}\left[\frac{T_{2}-T_{1}}{T_{1} T_{2}}\right]$
