Pressure in enthalpy vs heat capacity

Postby Lucia H 2L » Mon Jan 15, 2018 11:39 pm

There are different equations for heat capacity in the cases of standard pressure vs standard volume. Does the same apply to enthalpy? Or do we always assume standard pressure for equations outside of a calorimeter?

I think that unless stated, you assume standard pressure. Otherwise, there's really no way of knowing how to calculate it.

You always just use what they give you for enthalpies, but heat capacity is definitely more specific. So yes, it does depend on whether the pressure/volume is constant for heat capacity.
