(a) It is impossible to have all these pressures with the same value, because if so: $$K_p = \frac{P_{CO_2}P_{H_2}}{P_{CO}P_{H_2O}} = 1$$ And, as we know, Kp is not equal to 1. False (c) Substitute: $$K_p = \frac{P_{CO}P_{H_2O}}{P_{CO}P_{H_2O}} = 1$$ And, as we know, Kp is not equal to 1. False - The other two alternatives (b) and (d) are possible, since we cannot do the same substitutions and have a False result.
