Chemistry 3A

An aqueous solution contains the ions B, C, and D that are in equilibrium with one another according to the reaction

B (aq) + C (aq) ->/<- D (aq)


A certain amount of water is added so as to double the volume of this solution, while keeping the temperature and the pressure constant. Answer the following question for the instant after the water is added but before the equilibrium shifts.

1) The instant after the water has been added, the value of the reaction quotient for this reaction has

(a) increased
(b) decreased
(c) remained the same


2) The instant after the water has been added, the value of the equilibrium constant for this reaction has

(a) increased
(b) decreased
(c) remained the same


I thought that it will remain the same as water is added. Only reactants and products can change equilibrium before/after


Thanks for any help
