5.2.2 (a,b,c) Etropy

(a) explanation that entropy is a measure of the dispersal of energy in a system which is greater, the more disordered a system

(b) explanation of the difference in magnitude of the entropy of a system:

(i) of solids, liquids and gases

(ii) for a reaction in which there is a change in the number of gaseous molecules

(c) calculation of the entropy change of a system, ∆S, & related quantities for a reaction given entropies of reactants & products
