An electrochemical cell is set up as follows :
`Pt (H_(2)` , atm ) | 0.1 M HCl |0.1 M acetic acid | `(H_(2) , `1 atm ) Pt
EMF of this cell will not be zero because
A. the temperature is constant
B. the pH of 0.1 M HCl and 0.1 M acetic acid is not the same
C. acids used in the two compartments are different
D. EMF of a cell depends on molarities of the acids used.

Correct Answer - B
It is a concentration cell . EMF `ne 0` because 0.1 MHCl and 0.1 M `CH_(3)COOH` have different `[H^(+)]` , i.e., their pH are not equal .
