Question

Write the equilibrium-constant expression for the reactionA(s)+3B(l)↽−−⇀2C(aq)+D(aq)A(s)+3B(l)↽−−⇀2C(aq)+D(aq)in terms of [A], [B], [C], and [D] as needed.Note that KcKc, which is sometimes symbolized as KeqKeq, denotes that the equilibrium constant is expressed using molar concentrations. For this question, KcKc means the same thing as KeqKeq.Kc=___________.

Answer 1

Answer:

$K_{c} = [\text{C}]^{2}[\text{[D]}$

Explanation:

$\rm A(s)+3B(l) \, \rightleftharpoons \, 2C(aq)+D(aq)$

The general formula for an equilibrium constant expression is

$K_{c} = \dfrac{[\text{Products}]}{[\text{Reactants}]}$

Solids and liquids are not included in the equilibrium constant expression.

Thus, for this reaction,  

$K_{c} = [\textbf{C}]^{\mathbf{2}}\textbf{[D]}$
