Problem

Water gas, a mixture of H2 and CO, is an important industrial fuel produced by the reaction of steam with red hot coke, essentially pure carbon.

(a) Write the expression for the equilibrium constant for the reversible reaction
C(s) + H2O(g) ⇌ CO(g) + H2(g) ΔH = 131.30 kJ
(b) What will happen to the concentration of each reactant and product at equilibrium if more C is added?
(c) What will happen to the concentration of each reactant and product at equilibrium if H2O is removed?
(d) What will happen to the concentration of each reactant and product at equilibrium if CO is add
ed?

(e) What will happen to the concentration of each reactant and product at equilibrium if the temperature of the system is increased?
