$$N_2(g) + 3 H_2(g) ⇄ 2 NH_3(g) \quad ΔH = −92 \ \text{kJ}$$

Which of the following changes would NOT affect the value of $Q_p$?

A

Opening the sealed container to the surroundings.

B

Increasing the total pressure of the system by adding argon gas.

C

Placing the system in a flexible, sealed container, like a balloon.

D

Adding concentrated hydrochloric acid to the gaseous system.
