Question- In a dry cell, MnO2 occurs in a semisolid electrolyte paste and is reduced at the cathode. The MnO2 used in dry cells can itself be produced by an electrochemical process of which one half-reaction is shown below.
Mn2+(aq) + 2 H2O(l) MnO2(s) + 4 H+(aq) + 2 e -
If a current of 39.0 A is used, how many hours are needed to produce 1.50 kg of MnO2?
Any expert will able to provide correct answer for the above question.
