Which of the following expressions is the correct equilibrium constant expression for the reaction aA + bB ⇌ cC + dD?

A. [C]^c[D]^d/[A]^a[B]^b
B. [A]^a[B]^b/[C]^c[D]^d
C. [C][D]/[A][B]
D. [C][D]/[A]^a[B]^b

Answer: [C]^c[D]^d/[A]^a[B]^b


Additional Information: The equilibrium constant expression is based on the stoichiometric coefficients of the balanced equation.
