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 is added to raise the total pressure to 1.4 atm?A.The partial pressure of hydrogen will decrease
B. The partial pressure of hydrogen will increase
C. The partial pressure of hydrogen will be unchanged
D. Kp needs to be known before a prediction can be made
E. Both Kp and the temperature need to be known before a prediction can be made

Respuesta :

Answer:

The answer is C. The partial pressure of hydrogen will be unchanged.

Explanation:

[tex]CO_{(g)} + 2H_{2(g)}[/tex]  ⇒  [tex]CH_{3}OH[/tex]

Argon with electronic configuration [tex]1s^{2}[/tex]  [tex]2s^{2}[/tex]  [tex]2p^{6}[/tex]  [tex]3s^{2}[/tex]  [tex]3p^{6}[/tex] (that is atomic number 18) is an inert gas making it unreactive and it's addition to the reaction has no effect on the partial pressure of either the reactant or production or the state of the system.

The partial pressure of hydrogen will remain unchanged on the addition of Argon.
