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] = 0.0530 M, [H2] = 0.0400M, [CO2] = 0.0870 M, and [H2O] = 0.0350 M. (a) Calculate Kc for the reaction at 686°C. (b) If we add CO2 to increase its concentration to 0.450mol/L, what will the concentrations of all the gases be when equilibrium is reestablished
