Write the equilibrium‑constant expression for the reaction

A(s)+3B(l)↽−−⇀2C(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, Kc means the same thing as Keq.

Kc=
