1. Give the name for the iron coated with the Zinc.2. Can we store Cl2

1.	1. Give the name for the iron coated with the Zinc.2. Can we store Cl2 gas in copper vessel? Give reason.(E°(Cu2+/Cu) = + 0.34 V E°(Cl2/Cl-) = +1 -36 V)3. The equilibrium constant of a reaction which is difficult to calculate can be calculated by knowing the standard potential of the cell in which reaction takes place. Give the mathematical expression relating equilibrium constant and cell potential
Answer» 1. Galvanised iron 2. No. Since the reduction potential of chlorine is greater than that of copper,chlorine reacts with copper to form cuprous chloride. E°_(Cl²/Cl^-) > (E°_(Cu²⁺/Cu)) 3. E°_cell = \(\frac{2.303RT}{nF}logK_c\) where E°_cell is the standard cell potential (E°_cell = E°_cathode – E°_anode and K_c is the equilibrium constant of the cell reaction.

Answer»

1. Galvanised iron

2. No. Since the reduction potential of chlorine is greater than that of copper,chlorine reacts with copper to form cuprous chloride.

E°_(Cl²/Cl^-) > (E°_(Cu²⁺/Cu))

3. E°_cell = \(\frac{2.303RT}{nF}logK_c\)

where E°_cell is the standard cell potential (E°_cell = E°_cathode – E°_anode and K_c is the equilibrium constant of the cell reaction.
