Equilibrium Expressions |
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) ⇌ H 2(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 (K c) for the reversible reaction
2H2(g) + CO(g) ⇌ CH3 OH(g) ΔH = −90.2 kJ
