Review Question 14.10.

Write equilibrium constant expressions, Kp, for the following reactions.

(a) CO(g) + H2O(g)CO2(g) + H2(g)

(b) N2(g) + 3 H2(g)2 NH3(g)

(c) NH4HS(s)NH3(g) + H2S(g)




Answer:

Use the definition of mass action to write the equilibrium constant expression:

(a) CO(g) + H2O(g)CO2(g) + H2(g)



(b) N2(g) + 3 H2(g)2 NH3(g)



(c) NH4HS(s)NH3(g) + H2S(g)
