Methanol can be synthesized by combining carbon monoxide and hydrogen. CO(g) + 2H₂(g) CH3OH(g) A reaction vessel contains the three gases at equilibrium with a total pressure of 1.00 atm. What will happen to the partial pressure of hydrogen if enough argon (Ar) is added to raise the total pressure to 1.4 atm? O Both Kp and the temperature need to be known before a prediction can be made. O The partial pressure of hydrogen will increase. The partial pressure of hydrogen will be unchanged. O The partial pressure of hydrogen will decrease. O Kp needs to be known before a prediction can be made.
