Solution

The correct option is A evaluating rate constants at two different temperature
Activation energy of a chemical reaction can be determined by evaluating rate constants at two different temperature.It can be determined with the help of Arrhenius equation:
$2.303 l o g \frac{K_{2}}{K_{1}} = \frac{E_{a}}{R} [\frac{T_{2} - T_{1}}{T_{1} T_{2}}]$
