# Question: Given the following equilibrium constants at 427oC Na2O s 2Na l

Given the following equilibrium constants at 427oC,

Na2O(s) ⇌ 2Na(l) + 12 O2(g) K1 = 2 × 10-25

NaO(g) ⇌ Na(l) + l2 O2(g) K2 = 2 × 10-5

Na2O2(s) ⇌ 2Na(l) + O2(g) K3 = 5 × 10-29

NaO2(s) ⇌ Na(l) + O2(g) K4 = 3 × 10-14

determine the values for the equilibrium constants for the following reactions.

a. Na2O(s) + 12O2(g) ⇌ Na2O2(s)

b. NaO(g) + Na2O(s) ⇌ Na2O2(s) + Na(l)

c. 2NaO(g) ⇌ Na2O2(s) (Hint: When reaction equations are added, the equilibrium expressions are multiplied.)
