Sample Problem 20.1
SOLUTION:
Predicting relative entropy values
(a) 1 mol of SO2(g) or 1 mol of SO3(g)
(b) 1 mol of CO2(s) or 1 mol of CO2(g)
(c) 3 mol of oxygen gas (O2) or 2 mol of ozone gas (O3)
(d) 1 mol of KBr(s) or 1 mol of KBr(aq)
(e) seawater in mid-winter at 2 oC or in mid-summer at 23 oC
(f) 1 mol of CF4(g) or 1 mol of CCl4(g)
(a) 1 mol of SO3(g) - more atoms
(b) 1 mol of CO2(g) - gas > solid
(c) 3 mol of O2(g) - larger # mols
(d) 1 mol of KBr(aq) - solution > solid
(e) 23 oC - higher temperature
(f) CCl4 - larger mass
