Two correct statements about the reversible reaction N₂(g) + O₂(g) ⇌ 2 NO(g) are 

(a) K = K_p;

(b) The equilibrium amount of NO increases with an increased total gas pressure; 

(c) The equilibrium amount of NO increases if an equilibrium mixture is transferred from a 10.0 L container to a 20.0 L container; 

(d) K = K_c;

(e) The composition of an equilibrium mixture of the gases is independent of the temperature.
