Answer:
1. right 2. left 3. left 4. left 5. left
Explanation:
1. N2 is a reactant, so adding more will push the reaction away from N2 which will be right, towards the products
2. treat heat as a product, so by increasing temp you increase heat and you push the reaction away from heat which will be left, towards the reactants
3. Adding NH3 will push the reaction away from it, so it'll move left, towards reactants
4. When you decrease pressure, the reaction will move to the side with more moles, since the left side has 4 moles and the right only has 2, it'll move left
5. by removing H2, the equillibrium will shift left in order to restore balance.
