Use Le Chatelier’s principle to predict how the equilibrium concentration of the FeCl2+ ion will change when an aqueous solution of silver (I) nitrate, AgNO3, is added to the exothermic reaction below. Fe3+(aq) + Cl-(aq) → FeCl2+(aq)

The concentration of will decrease.

Explanation:

According Le Chatelier’s principle:

On ad adding silver nitrate to the equilibrium mixture, the silver ion will get combine with chloride ion to precipitate silver chloride which will in return will decrease the concentration of chloride ions.

And due to decrease in concentration of chloride ions the the equilibrium will shift in left direction that is in backward direction to re-establish it self with which concentration of will decrease.
