Write the equilibrium-constant expression for the reaction A(s) + 3B(1) 2 C(aq) + D(aq) in terms of [A], [B], [C], and [D], as needed. Note that Kc, which is sometimes symbolized as Keq, denotes that the equilibrium constant is expressed using molar concentrations. For this question, Ke means the same thing as Keq.
