Units when calculating reaction enthalpy

Postby Caitlin Mispagel 1D » Sun Jan 14, 2018 9:31 pm

Can someone explain when we are supposed to use kJ and when we use kJ/mol?

So, Standard Reaction Enthalpy of a reaction (for example, combustion) is often kJ. If they ask you for the Reaction Enthalpy of one mole of a substance, then it is kJ/mol. Standard Enthalpy of Formation is always kJ/mol.


Return to “Reaction Enthalpies (e.g., Using Hess’s Law, Bond Enthalpies, Standard Enthalpies of Formation)”
