Answer:
[tex]K_{eq}\text{ = }\frac{[CO_2][H_2O]\placeholder{⬚}^2}{[CH_4][O_2]\placeholder{⬚}^2}[/tex]
Explanation:
Here, we want to write the equilibrium constant expression
Generally, to write this, we exclude non-gaseous molecules
We simply put divide the concentration of the products (in square brackets) raised to the number of moles divided by that of the reactants raised to the number of moles too
For the given equation, we have the expression as:
[tex]K_{eq}\text{ = }\frac{[CO_2][H_2O]\placeholder{⬚}^2}{[CH_4][O_2]\placeholder{⬚}^2}[/tex]
