Will adding Ar(g) shift the equilibrium in 2NOCl(g) <--> 2NO(g) + Cl2(g)?

[bobbarkernar]

Homework Statement

For the equalibrium: 2NOCl(g)<-->2NO(g)+Cl2(g), delta G=+77.1kJ
Determine in which direction the equilibrium will shift by the following changes.

A) Ar(g) is added to the reaction

Homework Equations

The Attempt at a Solution

My first thought is that this will not alter the equilibrium as no change has been made to the individual parts of the chemical equation. I hope someone could point me in the right direction, if i am wrong or confirm that this is the right conclusion.

Thank you,

Are there any other conditions given? Ie constant pressure/volume. Because Argon is an inert gas, and in one of the two conditions, nothing changes. The other one does.

Constant volume, nothing changes. Constant pressure, things will change.
