1.	The cell voltage of a galvanic cell becomes zero after using for some tme becauseA. All the free electrons are used upB. Oxidation potential of the two half cell become differentC. Reduction potential of the two half cells become equalD. Oxidation potentials of two half cells become equal in magnitude but opposite in sign.
Answer» Correct Answer - C Since `E_("red")prop[M^(n+)]` `therefore` when current is drawn the conc. Of eec trolytic solution changes and hence the reduction potential.
