Equilibrium Expressions

Solution: Express the equilibrium constant for the following reaction.P4O10 (s) ⇌ P4 (s) + 5 O2 (g)A) K = [P4][O2]5 / [P4O10]B) K = [P4O10] / [P4][O2]5C) K = [O2] -5D) K = [O2]5E) K = [P4O10] / [P4][O2]1/5

Problem

Express the equilibrium constant for the following reaction.

P4O10 (s) ⇌ P(s) + 5 O(g)

A) K = [P4][O2]5 / [P4O10]

B) K = [P4O10] / [P4][O2]5

C) K = [O2-5

D) K = [O2]5

E) K = [P4O10] / [P4][O2]1/5
