Write the equilibrium constant expression Kc for the following reaction.2H20(g) ---------> O2(g) + 2H2(g) <---------Do not

Komok [63]

Answer:

$K_c\text{ = }\frac{[O_2][H_2]\placeholder{⬚}^2}{[H_2O]\placeholder{⬚}^2}$

Explanation:

Here, we want to write the equilibrium constant expression

To write this, we raise the concentrations of the reactants and products to the coefficient before them. These concentrations are represented by square brackets in which the chemical formula of the compound is placed

We place the representation of the products over that of the reactants

We have the expression written as follows:

$K_c\text{ = }\frac{[H_2]\placeholder{⬚}^2[O_2]}{[H_2O]\placeholder{⬚}^2}$
