Question
Water gas is a 1:1 mixture of carbon monoxide and hydrogen gas and is called water gas because it is formed from steam and hot carbon in the following reaction: H2 O(g) + C(s) ⇌ H2(g) + CO(g). Methanol, a liquid fuel that could possibly replace gasoline, can be prepared from water gas and hydrogen at high temperature and pressure in the presence of a suitable catalyst.
(a) Write the expression for the equilibrium constant (Kc) for the reversible reaction
2H2(g) + CO(g) ⇌ CH3 OH(g) ΔH = −90.2 kJ
(b) What will happen to the concentrations of H2, CO, and CH3OH at equilibrium if more H2 is added?
(c) What will happen to the concentrations of H2, CO, and CH3OH at equilibrium if CO is removed?
(d) What will happen to the concentrations of H2, CO, and CH3OH at equilibrium if CH3OH is added?
(e) What will happen to the concentrations of H2, CO, and CH3OH at equilibrium if the temperature of the system is increased?
(f) What will happen to the concentrations of H2, CO, and CH3OH at equilibrium if more catalyst is added?
