enthalpy vs energy???
why is the first ionisation energy defined as:
the ENERGY change that accompanies the removal of one mole of electrons... etc
rather than
the ENTHALPY change that accompanies the removal of one mole of electrons... etc
why other definitions like that of lattice enthalpy include enthalpy rather than energy? what is enthalpy?
the ENERGY change that accompanies the removal of one mole of electrons... etc
rather than
the ENTHALPY change that accompanies the removal of one mole of electrons... etc
why other definitions like that of lattice enthalpy include enthalpy rather than energy? what is enthalpy?

An enthalpy change is simply an energy change when done at constant pressure.
I'm not sure why IE is not defined in terms of H.
