Answer
To relieve the stress caused by increased pressure, the reaction will shift towards the side that has the less number of gas molecules, the right.
The addition of a catalyst is not related to the direction of equilibrium in a chemical reaction. It effects the rate of the reaction. No change , therefore will occur.
To relieve the stress caused by cooling the reaction mixture, the direction of the equilibrium will shift to the right , which produces heat , which compensates for the cooling of the reaction mixture.
