Chemistry

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 whensome O2 (g) is removed from the reaction mixture?

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

c) In which direction does the equilibrium shift as thetemperature is lowered?

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