4. A mixture of gases is at equilibrium: C2H6 (g) → C2H4 (g) + H2 (g) ∆H = 136.94 kJ (a) Does the equilibrium shift to the left or to the right when some C2H6 (g) is added to the reaction mixture? (b) Does the equilibrium shift to the left or to the right when some C2H4 (g) is added to the reaction mixture? (c) In which direction does the equilibrium shift as the temperature is lowered? (d) In which direction does the equilibrium shift as pressure is applied to the system?
