consider the following equilibrium process at 686°C:, CO2 (g)+ H2(g) = CO(g)+H2O (g).The equilibrium concentration of the reacting species are [CO] = 0.050 M, [H2] 0.045 M. [CO₂] = 0086 M,&[H2O ]=0.040M.(a) Calculate Kc for the reaction; at 686°C. (b) If we add CO2 to increase its concentration to
0.50 mol/L, what will the concentrations of all the gases be when equilibrium is reestablished?
