Fe(excess) + Cl2→Product XFe + Cl2 (excess) →Product Y , X and Y are respectively

Whenever a reaction between an oxidizing agent and a reducing agent is carried out :If reducing agent is in excess compound of lower oxidation state is formed X = FeCl2 ( iron is reducing agent in excess)If oxidizing agent is in excess compound of higher oxidation state is formed Y = FeCl3 (Chlorine is oxidizing agent in excess)
