Use Le Chantelier's principle

Explanation:

A) you're increasing the volume which means that the pressure decreases (they are inverserly proportional). if the pressure decreases, then to restore equilibrium the reaction will shift to the side with more moles of gas

B)Adding a catalyst will have no effect. A catalyst simply speeds up the rate of a reaction

C) If you increase the concentration of a substance, in order to restore equilibrium the reaction will shift away from the substance you're increasing the concentration of.

D) Treat temperature as if it was another reagent or product. Usually, where the heat is(product or reactant side) will be indicated in the equation. If you lower the temp you're removing it so it will shift towards it. It works the same way as concentration.
