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.
