Problem
Consider the dissociation reaction E₂(g) ⇌ 2 E(g) at a certain temperature. Three identical 1.0 L containers reach equilibrium, with the following particle counts:
• Container A: 40 E₂ and 0 E
• Container B: 30 E₂ and 20 E
• Container C: 10 E₂ and 30 E
Which ranking correctly orders the containers from LEAST to GREATEST extent of dissociation (product formation)?
(a) C<B<A
(b) A<B<C
(c) B<C<A
(d) C<A<B
