Balance each of the following examples of heterogeneous equilibria and write each kc expression. then calculate the value of kc for the reverse reaction.

(1) al(s) + naoh(aq) + h2o(l) ⇋ na[al(oh)4](aq) + h2(g) kc for balanced reaction = 11
(2) h2o(l) + so3(g) ⇋ h2so4 (aq) kc for balanced reaction = 0.0123
(3) p4(s) + o2(g) ⇋ p4o6(s) kc for balanced reaction = 1.56

Explanation:

1)

The Kc for the reverse reaction is the inverse of the Kc of the reaction:

2)

The Kc for the reverse reaction is the inverse of the Kc of the reaction:

3)  

The Kc for the reverse reaction is the inverse of the Kc of the reaction:
