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

### Re: Activation energy

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

### Re: 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.

### Re: Activation energy

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