Consider the following reaction at equilibrium:

Question

C(s) + H2O(g) CO(g) + H2(g)

Predict which of these stresses which cause the equilibrium system to shift towards the reactant side (to the left). (There may be more than one correct answer - choose ALL of the correct choices.)

a. C is added to the reaction mixture.
b. H2O is condensed and removed from the reaction mixture.
c. CO is added to the reaction mixture.
d. H2 is removed from the reaction mixture.
