Which is the correct equilibrium constant expression for the following reaction?

2 KClO3(s) ⇌ 2 KCl(s) + 3 O2(g)

A.	Kc = [KCl]2 [O2]3 / [KClO3]2

B.	Kc = [O2]3

Kc = [O2]

D.	Kc = [KCl]

E.	Kc = [KCl] [O2] / [KClO3]

Solutions

Expert Solution

For a general reaction

Generally we take the concentration term of components in solid state to be zero.

So here only O2 contributes to Kc.

The answer is (B).
