For the reaction of 2CO(g) + O2(9) -> 2C02(g), if the pressure of the reaction vessel is increased by adding He(g), the equilibrium will be reestablished by the reaction Marks: 1 (Note: For all equilibrium problems, the single direction arrow should be a double arrow representing an equilibrium.,) Choose one answer. C. shifting to the right by increasing the concentration of the products. b. shifting to the right by increasing the concentration of the reactants c. shifting to the left by increasing the concentration of the products. d. shifting to the left by increasing the concentration of the reactants. e. not changing as the change in pressure will not affect the equilibrium. C 14 Marks: 1 For the reaction of 2CO(g)02(9)->2CO2(g), increasing the temperature will cause the reaction to (Note: For all equilibrium problems, the single direction arrow should be a double arrow representing an equilibrium.)
