A
Keq = [B][C] / [A]^2
B
Keq = [B][C]^2 / [A]
C
Keq = [A] / [B][C]^2
D
Keq = [A][B][C]^2

Identify the balanced chemical equation: A(g) ⇌ B(aq) + 2C(aq).
Understand that the equilibrium constant expression, Keq, is derived from the concentrations of the products over the reactants, each raised to the power of their stoichiometric coefficients.
For the given reaction, the products are B and C, and the reactant is A. The stoichiometric coefficient for B is 1 and for C is 2.
Write the equilibrium constant expression: Keq = ([B]^1 * [C]^2) / [A]^1.
Simplify the expression to: Keq = [B][C]^2 / [A].
