The activation energy of a reaction is 75.2 kJ mol–1 in the absence of a catalyst and 50.14 kJ mol–1 with a catalyst. How many times will the rate of reaction grow in the presence of the catalyst if the reaction proceeds at 25°C?
(R = 8.314 J K–1 mol–1)
By using the Arrhenius equation, we obtained
The rate of reaction will grow up by 25000 times in presence of catalyst. The decrease in activation energy takes place by 25.1 kJ mol–1.
