units for reaction enthalpy and enthalpy of formation

[Brian Tangsombatvisit 1C]

I've seen kJ and kJ/mol being used interchangeably for both reaction enthalpy and enthalpy of formation, so are either units okay? Or does enthalpy of formation typically have units of kJ/mol and does reaction enthalpy typically have units of just kJ?

I'm not too sure about my answer, but I believe that you can use them interchangeably.

I think you can use both. If it just says kJ it usually means per mole unless otherwise stated.

You can use both interchangeably. According to my TA (Dane), the per mol part simply clarifies that we are calculating the energy absorbed/release if the entire reaction occurred 1 mol times. Hope this helps!
