When heated, carbon reacts with water to produce carbon monoxide and hydrogen. C(s) + H2O + heat<>CO(g) + H2(g). for each of the following changes at equilibrium, indicate whether the equilibrium shifts toward products or reactants or does not shift: a)increasing the temperature. b)adding C(s). c)removing CO(g) as it forms. d)adding H2O(g). decreasing the volume of the container.
