Chapter 16, Problem 89QAP

Consider the following reaction with its thermodynamic data:
$2\text{A}\left(g\right)+{\text{B}}_2\left(g\right)\to 2\text{AB}\left(g\right)\Delta H°<0;\Delta S°<0;\Delta G°\text{at}60°C=+10\text{kJ}$
Which statements about the reaction are true?
(a) When $\Delta G=1$ , the reaction is at equilibrium.
(b) When $Q=1,\Delta G=\Delta G°$ .
(c) At 75°C, the reaction is definitely nonspontaneous.
(d) At 100°C, the reaction has a positive entropy change.
(e) If A and B₂ are elements in their stable states, S° for A and B₂ at 25°C is 0.
(f) K for the reaction at 60°C is less than 1.
