Cell notation of a galvanic cell is represented as Emf of the cell is minimum when the values of and are
Anode (LHE)
Cathode (RHE)
Net cell reaction :
Thus lesser the product of higher will be the ;
The product of in each case is
(1) option ….
(2) option ….1
(3) option ….
(4) option ….
Minmum emf of the cell is when =1 M and =1 M
