Chemistry equilibrium question

  1. Apr 4, 2007 #1
    1. The problem statement, all variables and given/known data

    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

    2. Relevant equations

    3. 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.
