Problem
For the reaction
E(g) ⇌ F(g),
the equilibrium constant at a certain temperature is K=2.5. Two identical containers at that temperature are observed:
• Container 1: 30 particles of E and 75 particles of F
• Container 2: 50 particles of E and 80 particles of F
Which container(s) are at equilibrium with respect to this reaction?
(a) Only Container 2
(b) Both Container 1 and Container 2
(c) Only Container 1
(d) Neither container
