The lattice energy of KCI is -690. kJ/mol, and the enthalpy of hydration is -707 kJ/mol. (Recall that lattice energy is defined as the energy change for the process M*(g) + X(g) → MX(s).) (a) Calculate the enthalpy of solution (in kJ/mol) per mole of solid KCI. kJ/mol (b) Describe the process to which this enthalpy change applies. AH soln refers to the heat released or gained when a a solute dissolves in a solvent
