An equilibrium mixture contains 0.450 mol of each of the products (carbon dioxide and hydrogen gas) and .200 mol of each of the reactants (carbon monoxide and water vapor) in a 1.00 L container.
CO(g) + H2O (g) (equilibrium to) CO2 (g) + H2 (g)
How many moles of carbon dioxide would have to be added at constant temperature and volume to increase the amount of carbon monoxide to .300 mol?
