2) Given this reaction at equilibrium: N2 (g) + 3 H2 (g) 2 NH3(g) In which direction toward reactants or toward products- does the reaction shift if the equilibrium is stressed by each change? 1. H2 is added. 2. NH3 is added. 3. NH3 is removed. 4. Decreasing volume 5. Increasing the pressure of gases
