Which of the following correctly represents the equilibrium constant of the above reaction?
A. C.
B. D.
D
The expression for the equilibrium constant has the concentrations of the products in the numerator and the concentrations of the reactants in the denominator. The concentration of a substance is raised to a power equal to its stoichiometric coefficient in the balanced chemical equation. Make sure you understand the differences between using the stoichiometric coefficients or deriving the rate law and equilibrium constant.
