Here are the solutions to the questions: 2. (a) Consider the energy level diagram below The overall reaction shown is the atomization of liquid phosphorus trichloride: PCl_3(l) P(g) + 3Cl(g) H = +982 kJ We can use Hess's Law by following the steps in the diagram: 1. Reverse of enthalpy of formation of PCl_3(l): PCl_3(l) P(s) + (3)/(2)Cl_
