Chapter 15 - Chemical Equilibrium - Exercises - Page 663: 15.16f


$K_{c}$ = $\frac{[CO_{2}]^{16} [H_{2}O]^{18}}{[O_{2}]^{25}}$ This is a heterogeneous reaction.

Work Step by Step

In a balanced chemical equation, the expression of the equilibrium constant is the product of the concentration of products raised to the power of their coefficients divided by the product of the concentration of reactants raised to the power of their coefficients. Also, Pure solids and liquids are not included in the expression of equilibrium constant. Thus, $K_{c}$ = $\frac{[CO_{2}]^{16} [H_{2}O]^{18}}{[O_{2}]^{25}}$ This is a heterogeneous reaction because the components of this reaction are in different physical states, liquid and gases.
