Explanation / Answer

1. P is an electronegative atom. For the given equation, energy will be released when electron is removed from the atom.

Yes it is possible to calculate the energy released.

Addition of one electron to P takes 72 kJ/mol of energy and forms P-.

Hence, energy released when P- releases one electron = -72 kJ/mol

2. P+ is unstable in nature. To remove one electron from P atom will absorb energy.

Yes it is nothing but the ionization energy that is used to remove one electron from P atom = 1011.8 kJ/mol
