1 mole of electrons is passed through three electrolytic cells in series , first containing silver ions, the second zinc ions and third ferric ions, assuming that the only cathode reaction in each cell reduces the ions to the metal , the number of moles of each metal deposited will be

Options

A. Ag(0.3 mol),Zn(1mol),Fe(1 mol)
B. Ag(0.5 mol), Zn(0.33 mol), Fe(1 mol)
C. Ag(1 mol), Zn(0.5 mol), Fe (0.33 mol)
D. Ag(0.5 mol),Zn(1 mol),Fe(0.33 mol)

Answer

C

Explanation

`Ag^(+)+e^(-) to Ag, Zn^(2+)+2e^(-) to Zn, Al^(3+)+3e^(-) to Al`
