Free energy

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
– explain dynamic equilibrium in terms of free energy change.
