At the end of this activity, students should be able to define free energy change and use it to determine whether a reaction is feasible or not, discuss the effect of ?H° and ?S° values on free energy change, explain why most exothermic processes are spontaneous but only certain endothermic processes are spontaneous, discuss how lattice formation enthalpy, enthalpy of hydration and entropy change affect the solubility of ionic compounds in water, correlate the feasibility of a reaction with the temperature and explain dynamic equilibrium in terms of free energy change.
