Sample Problem 17.11
SOLUTION:
Predicting the effect of a change in concentration on the equilibrium position
What happens to:
(a) [H2O] if O2 is added?
(b) [H2S] if O2 is added?
(c) [O2] if H2S is removed?
(d) [H2S] if sulfur is added?
(a) When O2 is added, Q decreases and the reaction progresses to the right to come back to K. Thus, [H2O] increases.
(note that [S] is absent from this expression)
