76. Coal can be used to generate hydrogen gas (a potential fuel) by this endothermic reaction.
C(s) + H2O(g) = CO(g) + H2(g)
If this reaction mixture is at equilibrium, predict the effect (shift right, shift left, or no effect) of the following:
a. adding more C to the reaction mixture
b. adding more H2O(g) 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
