Question

If M, N, O, P and Q are in the increasing order of their standard potentials in standard conditions of their standard half cells, then by combination of which two half cells maximurn cell potential will be obtained? Select the proper choice from the given multiple choices.
(A) M and N
(B) M and Q
(C) M and P
(D) M and O

Answer 1

greater the difference between to half cell potential higher is the cell potential because cell potential is differnece of two half cell

Answer 2

Answer: (B) M&Q

Explanation: because more the difference between the standard electric potential more the cell potential
