Carbon monoxide reacts with steam to produce carbon dioxide
and hydrogen. At 700 K the equilibrium constant is 5.10. Calculate
the equilibrium concentrations of all species if 1.000 mole of each
component (reactants and products) is mixed in a 1.000 L flask.
(Note: Be sure to check Q to determine which way the reaction will
proceed to come to equilibrium). Please show step by step, I'm
lost. Thank you!

CO(g) + H2O(g) -> CO2(g) + H2(g)
I 1 1 1 1
C -x -x +x +x
E 1-x 1-x 1+x 1+x
Kc = [Co2][H2]/[CO][H2O]
5.1 = (1+x)*(1+x)/(1-x)*(1-x)
5.1 = (1+x/1-x)2
2.25 = 1+x/1-x
2.25*(1-x) = 1+x
x = 0.385
[CO2] = 1+x = 1+0.385 = 1.385M
[H2] = 1+x = 1+0.385 = 1.385M
[CO] = 1-x = 1-0.385 = 0.615M
[H2O] = 1-x = 1-0.385 = 0.615M

Iron (III) oxide reacts with carbon monoxide to produce iron and
carbon dioxide:
Fe2O3 (s) + 3CO(g) 2Fe (s) + 3 CO2 (g)
54.4 g of Fe2O3and 24.7 g of CO react to produce iron.

The steam reforming of methane is an industrial which produces
carbon monoxide and hydrogen as feedstocks for other materials.
This reaction is normally run anywhere between 750 and 1100 C. When
the reaction is run in a large excess of water, it displays first
order kinetics with respect to the concentration of methane and
zeroeth order kinetics with respect to water. At 750 degrees, the
half-life of this reaction under these conditoins is 67.5 minutes.

At 700 K acetaldehyde decomposes in the gas phase to methane and
carbon monoxide. The reaction is:
CH3CHO(g)→CH4(g)+CO(g)
A sample of CH3CHO is heated to 700 K and the pressure is measured
as 0.27 atm before any reaction takes place. The kinetics of the
reaction are then followed by measurements of total pressure and
