Will increasing the activation energy increase or decrease the rate of a reaction?
From the Arrhenius equation the activation energy (
#k = Acdot"exp"(-(E_a)/(RT))#, #" "#where #e^x -= "exp"(x)#
Higher activation energies decrease the rate of a reaction. That is the main reason catalysts are so important in the chemical industry. Catalysts reduce the activation energy, allowing for more effective and efficient processes.
