Chemistry

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 = -205.9kJ/mol

1.Write the equilibrium constant expression for reaction 3.

2. For all three reactions, predict the way the equilibrium willshift in response to an decrease in pressure. EXPLAIN.

3. For all three reactions, predict the direction in which eachequilibrium shifts in response to an increase in reaction volume.EXPLAIN.
