The electron gain enthalpy ΔegH of Cl(g) is -349 kJ mol-1. If the ground state energy of Cl(g) is x kJ mol-1,the ground state energy in kJ mol-1 of Cl-(g) is
  1. x+349
  2. x
  3. x-349
  4. x-34917

Solution

Cl2→∆egH 2Cl-+ 2e-As ground state energy is x kJ mole-1,x=∆Eground state - ∆egH∆Eground state=x+∆egH∆Eground state=x-349
