Calculate ionisation potential of the electron in the first exited state of singly ionised Helium atom is given by ionisation of Hydrogen atom to be 13.6 eV. Ans: According to
Enthalpy, H, is defined by the relationship H=U+pV. The enthalpy change, ΔH, for finite changes at constant pressure is given by the expression ΔH = ΔU+pΔV, so making the enthalpy
