The reduction of carbon dioxide by hydrogen gas takes place at 420°C to produce water vapor and carbon monoxide. The equation for
this reaction at equilibrium is shown below.
H2(g) + CO2(g) = H2O(g) + CO(g)
Which of the following changes in concentration occur when more water vapor is added to the system under equilibrium conditions?
O A [Hz] decreases, [CO] decreases, [CO] increases
OB (H) increases, (CO2) increases, [CO] decreases
OC [Hz, increases, [CO2, increases, [CO] increases
D. [H2, decreases, [CO] decreases, [CO] decreases
