Electromotive force is an intensive property. It is

Options

A. independent of the equilibrium constant of the reaction under study
B. Independent of the tempreature of the solution under study
C. dependent on the volume of the solution and independent of the size of the electrodes
D. independent of the volume of the solution and the size of the electrodes.

Answer

D

Explanation

Chemical analysis shows that the dark colured deposit is finely divided copper metal abnd that the solution now contains zinc ions. Therefore the reaction is
`Zn(s)+Cu^(2+)(aq.) rarr Zn^(2+)(aq.)+Cu(s)`
This is a redox reaction is which `Zn` met
