The rate of the reaction quadruples when the temperature changes from $293 K$ to $313 K$ .Calculate the energy of activation?

Open in App

Solution

$l o g \frac{k_{2}}{k_{1}} = \frac{E_{a}}{2.303 \times R} (\frac{1}{T_{1}} - \frac{1}{T_{2}})$

$l o g 4 = \frac{E_{a}}{2.303 \times 8.314} (\frac{1}{293} - \frac{1}{313})$

$E_{a} = 52.86 k J {m o l}^{- 1}$
