Question

Identify the substances that will appear in the equilibrium constant expression for the equation: 2 upper A g superscript plus (a q) plus upper Z n (s) double arrow upper Z n superscript 2 plus (a q) plus 2 upper A g (s). Check all that apply. Ag Zn Zn2 Ag.

Answer 1

Equilibrium constant is the ratio of the product and reactant at the equilibrium condition. The elements appear in the equilibrium constant expression are  Ag, and Zn.

What is the expression of equilibrium constant?

The equilibrium constant is the reaction quotient with the ratio of concentration of product concentration to reactant concentrations at the equilibrium.

The given reaction is expressed as:

$\rm 2\;Ag^+\;+Zn\;\rightarrow\;Zn^2^+\;+2\;Ag$

The equilibrium constant for the reaction is given as;

$\rm Equilibrium \;constant=\dfrac{[Zn^2^+][Ag]^2}{[Ag^+]^2[Zn]}$

The species involved in the equilibrium constant are Ag and Zn.
