What happens to the equilibrium between NO2(g) and N2O4(g) in inert argon when the volume is increased and additional argon is a
Korvikt [17]

Answer:

Equilibrium will be shifted towards NO2 as it has the most of the moles in the reaction.

Explanation:

Hello there!

In this case, according to the equilibrium reaction between NO2 and N2O4, we are able to write:

2NO_2(g)\rightleftharpoons N_2O_4(g)

We can recall the LeCha-telier's principle to realize that the increase of volume promotes the formation of the most of the moles, this is for NO2 because it has a coefficient of 2 and N2O4 a coefficient of 1; in such a way, we infer that the addition of argon, to increase the pressure, will shift the equilibrium towards NO2.

Regards!
