(Answered) A mixture of gases is at equilibrium4 no g rarr 2 n2o g o2

Academics

A mixture of gases is at equilibrium:

4 NO (g) → 2 N2O (g) + O2 (g) ?H = -199.5 kJ

(a) Does the equilibrium shift to the left or to the right when some O2 (g) is removed from the reaction mixture?

(b) Does the equilibrium shift to the left or to the right when some NO (g) is added to the reaction mixture?

(d) In which direction does the equilibrium shift as pressure is applied to the system?
