Answer:
Kₑq = [H₂]² [O₂] / [H₂O]²
Step-by-step explanation:
We'll begin by defining equilibrium constant for a reaction. This is given below:
The equilibrium constant for a given reaction is defined as the ratio of the concentration of the products raised to their coefficient to the concentration of the reactants raised to their coefficient.
With the above information in mind, we shall determine the equilibrium constant for the reaction given in the question above. This is illustrated below:
2H₂O (g) <=> 2H₂ (g) + O₂ (g)
Kₑq = [H₂]² [O₂] / [H₂O]²
