enthalpy unit

[tierra parker 1J]

what are the units for enthalpy, is it just joules?

[Danielle_Gallandt3I]

I think it depends, because the standard enthalpy of formation is in J/mol, so I think it changes with the "type" of enthalpy you are considering

[Philipp_V_Dis1K]

Usually one assumes that a certain amount of energy (joules) is released or used up during a reaction of 1 mole. Therefore it can be J/mol or kJ/mol

[Sarah Fatkin 4I]

Most of the problems we do require enthalpy in joules, because delta(H) = detla(U) + pV, where detla(U) is in joules and pV can easily be converted into joules with the constant 101.325 J/(atm*L). Also, delta(H) is just H[final] - H[initial], both of which are in joules. Hope this helps!
