Delta H and what it represents

Postby HoganFenster2E » Mon Jan 18, 2016 12:06 pm

When do we know Delta H is pr mole. I though that Delta H was just the energy in Joules, however in homework problem 8.45 the Delta H is per mole according to the solutions manual. Also, how do we know what Delta H is representing in different problems?

DeltaH is always the heat transferred at constant pressure. The units of the answer are kJ/mol if you do not know how much moles there were. If the moles is given, then you would multiply by that to get kJ.
