What is the equilibrium constant of 2H, 0 = 2H2 + 0,?

K = [H₂]² [ O₂] / [H₂O]²

Explanation:

The equilibrium constant of any reaction can be written as,

K = [product] / [reactant]

For given reaction:

Chemical equation:

2H₂O → 2H₂ + O₂

equilibrium constant:

K = [H₂] [ O₂] / [H₂O]

In stoichiometric calculations, we will put the coefficient of balanced equation in given equilibrium constant equation.

K = [H₂]² [ O₂] / [H₂O]²
