Consider the reaction N2(g) + 3 H2(g) <=> 2 NH3(g), which is exothermic as written. What would be the effect on the equilibrium position of adding a suitable catalyst? 1. Reaction would go to the left, making more "reactants" 2. Reaction would go to the left, making more "products" 3. No change on the equilibrium position 4. Reaction would go to the right, making more "reactants" 5. Reaction would go to the right, making more "products"
