4. Consider the reaction
CO (g) +
CH3OH (9)
An initial reaction mixture in a 5.19 L flask at a certain temperature contains 26.9g of CO and 2.34g
of H₂. At equilibrium, the flask contains 8.65g of CH3OH. Calculate the equilibrium constant, Kc,
for the reaction at this temperature.
5. Consider the reaction:
CO (g) +
2 H₂ (9)
H₂O (g)
CO₂ (g) + H₂ (g)
If a reaction mixture initially contains 0.110 M CO and 0.110 M H₂O, what will be the equilibrium
concentration of each of the reactants and products?
Kc = 102 at 500 K.
