Answer Key:
33.
89.3 J/K‧mol
47.
a. ΔH and ΔS are both negative;
b. low temeratures
57.
a. 53 kJ;
b. No, the reaction is not spontaneous at standard concentrations and 298 K.
65.
8.72; 0.0789
71.
ΔH。 = 1.1 x 10^5 J/mol; ΔS。 = 330 J/K‧mol;
the major diference in the plot is the slope of the line. An endothermic
process has a negative slope for the ln(K) versus 1/T plot, whereas an
exothermic process has a positive slope.
