Consider the following equilibrium process at 686°C:CO2(g) + H2(g) CO(g) + H2O(g)The equilibrium concentrations of the reacting species are [CO] = 0.050 M, [H2] = 0.045 M, [CO2] = 0.086 M, and [H2O] = 0.040 M. (a) Calculate Kc for the reaction at 686°C. (b) If we add CO2 to increase its concentration to 0.25 mol/L, what will the concentrations of all the gases be when equilibrium is reestablished?
