Final answer:
The equation A(aq) + 2B(aq) ⇌ 2C(aq) represents the reaction. The mathematical expression for the equilibrium constant, Kc, is [C(aq)]^2 / [A(aq)] * [B(aq)]^2. The subject of this question is Chemistry for High School students.
Step-by-step explanation:
The equation A(aq) + 2B(aq) ⇌ 2C(aq) represents the reaction in question. In order to write the mathematical expression for the equilibrium constant, Kc, we need to express the concentration of the products over the concentration of the reactants. In this case, Kc = [C(aq)]^2 / [A(aq)] * [B(aq)]^2. Therefore, the correct answer is (c) A + B ⇌ C.
