Suppose you have the following chemical reaction at equilibrium: N2H4 (1) + N2O4 (1) = N2 (g) + H2O (g) If this reaction releases heat, what direction will the equilibrium shift when: 1. the amount of N2 is decreased? 2. the heat of the system is increased? 3. an inert gas with pressure 3.00 atm is placed in the system? 4. the volume of the system is reduced? 5. a catalyst in the reaction is placed?
