(Please answer only the incorrect answer)
Be sure to answer all parts. Consider the following equilibrium process at 686∘C : CO2​(g)+H2​(g)⇌CO(g)+H2​O(g) The equilibrium concentrations of the reacting species are [CO]=0.0540M,[H2​]=0.0430M, [CO2​]=0.0810M, and [H2​O]=0.0380M. (a) Calculate Kc​ for the reaction at 686∘C. (b) If we add CO2​ to increase its concentration to 0.420 mol/L, what will the concentrations of all the gases be when equilibrium is reestablished? CO2​ x H2​ : × CO: H2​O : ×
