Content
Energy changes (ΔH) accompanying physical and chemical changes; dissolution of substances in water or reactions with water, including Na, NaOH, K and NH4Cl; endothermic (+ΔH) and exothermic (-ΔH) reactions.
Objective
Determine the types of heat changes in physical and chemical processes; interpret graphical representations of heat changes.
Content
Entropy as an order-disorder phenomenon, illustrated by mixing gases and dissolving salts.
Objective
Relate the physical state of a substance to its degree of orderliness.
Content
Spontaneity of reactions; ΔG° = 0 as a criterion for equilibrium; ΔG greater than zero for non-spontaneity and ΔG less than zero for spontaneity.
Objective
Determine the conditions for spontaneity; relate ΔH°, ΔS° and ΔG° as driving forces for chemical reactions; solve simple problems using ΔG° = ΔH° - TΔS°.
