Question
If the following reaction were at equilibrium in a closed vessel at a controlled temperature, what would be the effect of adding more H2 to the reaction vessel and permitting the reaction to approach equilibrium again.
CO + H2O <==> CO2 + H2
a. The concentrations of CO, H2O, and H2 would all increase.
b. The concentrations of CO, H2O, and H2 would all decrease.
c. The concentrations of CO and H2O would increase and the concentration of CO2 would decrease.
d. The concentrations of CO and H2O would decrease and the concentration of CO2 would increase.
Explanation / Answer
CO + H2O <==> CO2 + H2
The adding of H2 concentration at products side . The equlibrium shift to left side. So Concentation of CO , H2O increases and concentration of Co2 decreases.
c. The concentrations of CO and H2O would increase and the concentration of CO2 would decrease.
