Q. Activation energy of a chemical reaction can be determined by
A) Evaluating rate constant at standard temperatures
B) Evaluating velocities of reaction at two different temperatures
C) Evaluating rate constants at two different temperatures
D) Changing concentration of reactants
Explanation
(c)
Activation energy of a chemical reaction can be determined by evaluating rate constants at two different temperatures
$\log\frac{k_{2}}{k_{1}} = \frac{E_{a}}{2.303\ R}\left( \frac{1}{T_{1}} - \frac{1}{T_{2}} \right)$
