A mixture of gases is at equilibrium:

2 NOCl (g) → 2 NO (g) + Cl2 (g)

∆H = 78.38 kJ

(a) Does the equilibrium shift to the left or to the right when some NO (g) is removed from the reaction mixture?

(b) Does the equilibrium shift to the left or to the right when some NOCl (g) is removed from 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?
