Hydrogen and carbon dioxide gases react at a high temperature to give water and carbon monoxide: H2(g) + CO2(g) 2 H20(g) + CO(g) a. Laboratory measurements at 986°C show that there are 0.11 mol each of CO(g) and H2O(g), and 0.087 mol each of H2(g) and CO2(g) at equilibrium in a 1.00 L container. Calculate the equilibrium constant for the reaction at 986°C. b. Suppose 0.050 mol each of H2(g) and CO2(g) are placed in a 2.00 L container. When equilibrium is achieved at 986°C, what amounts of CO(g) and H20(g), in moles, would be present?

Question
Hydrogen and carbon dioxide gases react at a high temperature to give water and carbon
monoxide: H2(g) + CO2(g) 2 H2O(g) + CO(g)
a. Laboratory measurements at 986°C show that there are 0.11 mol each of CO(g) and
H2O(g), and 0.087 mol each of H2(g) and CO2(g) at equilibrium in a 1.00 L container.
Calculate the equilibrium constant for the reaction at 986°C.
b. Suppose 0.050 mol each of H2(g) and CO2(g) are placed in a 2.00 L container. When
equilibrium is achieved at 986°C, what amounts of CO(g) and H20(g), in moles, would
be present?
