Answer: The equilibrium constant expression for the given system is [tex]K_{eq}=\frac{[CO_2]}{[O_2]}[/tex]
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric coefficients. It is represented by [tex]K_{eq}[/tex]
For a general chemical reaction:
[tex]aA+bB\rightarrow cC+dD[/tex]
The [tex]K_{eq}[/tex] is written as:
[tex]K_{eq}=\frac{[C]^c[D]^d}{[A]^a[B]^b}[/tex]
The concentration of pure solid and pure liquid are taken as 1 in equilibrium expression.
The [tex]K_{eq}[/tex] for the given reaction is written as:
[tex]C(s)+O_2(g)\rightarrow CO_2(g)[/tex]
[tex]K_{eq}=\frac{[CO_2]}{[O_2]}[/tex]
