Coal can be used to generate hydrogen gas by this endothermic reaction:

Question

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

If this reaction is at equilibrium, which of these stresses would increase the formation of hydrogen gas? (choose ALL of the possible answers - there may be more than one.)

a. Adding more C to the reaction mixture.
b. Adding more H2O to the reaction mixture.
c. Raising the temperature of the reaction mixture.
d. Increasing the volume of the reaction mixture.
e. Adding a catalyst to the reaction mixture.
f. Adding an inert gas to the reaction mixture.
