Predict the effect on the amount of CO2 in the reaction mixture (increase, decrease, no charge) when the following stresses are applied to the reaction at equilibrium. 2 Co(g) 2 2c0,(g) + C(s) AH = -173 kl/mol a. CO is removed from the system. b. The reaction is heated. c. The amount of C(s) is decreased. d. The pressure is increased.
