Either Joules or Kilojoules per mole depending on the context of the problem

The activation energy of a reaction is measured in joules (J), kilojoules per mole (kJ/mol) or kilocalories per mole (kcal/mol)

Since its energy, its unit can be Joules or kJ.

How does a catalyst affect the activation energy?

Its energy so joules or kilojoules are acceptable. However, when using the Arrhenius equation or something of that sort ensure units cancel properly.

As far as I know, it is measured in J/M or kJ/M
