Some of the reactions for coal gasification are as follows:
Reaction 1: C(s) + H2O(g) « CO(g) + H2(g) ΔHo = 131.3 kJ/mol
Reaction 2: CO(g) + H2O(g) «CO2(g) + H2(g) ΔHo = -41.2 kJ/mol
Reaction 3: CO(g) + 3H2(g) O(g) « H2O(g) + CH4(g) ΔHo = -205.9 kJ/mol
1.Write the equilibrium constant expression for reaction 3.
2. For all three reactions, predict the way the equilibrium will shift in response to an decrease in pressure. EXPLAIN.
3. For all three reactions, predict the direction in which each equilibrium shifts in response to an increase in reaction volume. EXPLAIN.
