Question

The cell voltage of a galvanic cell becomes zero after using for some time because (A) All the free electrons are used up (B) Oxidation potentials of the two half cells become differen (C) Reduction potentials of the two half cells become equa (D) Oxidation potentials of two half cells become equal in magnitude but opposite in sign

Since Ered propto [Mn+] ∴ When current is drawn the cone, of electrolytic solution changes and hence the reduction potential.

Q. The cell voltage of a galvanic cell becomes zero after using for some time because

All the free electrons are used up

Oxidation potentials of the two half cells become differen

Reduction potentials of the two half cells become equa

Oxidation potentials of two half cells become equal in magnitude but opposite in sign

Since $E_{re d} \propto [M^{n +}]$
$∴$ When current is drawn the cone, of electrolytic solution changes and hence the reduction potential.
