Review Question 14.11

Write an equilibrium constant expression, Kp, based on the formation of one mole of each of the following gaseous compounds from its elements at 25 oC.

(a) NO(g) (b) NH3(g) (c) NOCl(g)






Answer:

In each case, first write the balanced chemical reaction and then use the stoichiometric coefficients in the mass action expression to give the equilibrium constant expression.

(a) ½N2(g) + ½O2(g) NO(g)

(b) ½N2(g) + H2(g) NH3(g)

(c) ½N2(g) + ½O2(g) + ½Cl2(g)NOCl(g)
