Problem
The reaction F(g) + G(g) ⇌ FG(g) has Kc=0.10 at a certain temperature. Four identical containers (I–IV) at that temperature contain the following mixtures.
Container I : 10 F, 10 G, 10 FG
Container II : 8 F, 8 G, 4 FG
Container III : 6 F, 12 G, 7 FG
Container IV : 12 F, 4 G, 6 FG
Which container is at equilibrium?
(a) Container III
(b) Container II
(c) Container I
(d) Container IV
