Ncert Exercises & Solutions

The correct statement among the following options is:

1.	E_cell and ∆_rG of cell reaction are both extensive properties.
2.	E_cell and ∆_rG of cell reaction are both intensive properties.
3.	E_cell is an intensive property while ∆_rG of cell reaction is an extensive property.
4.	E_cell is an extensive property while ∆_rG of cell reaction is an intensive property.

HINT: An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured.

Explanation:

E_cell is an intensive property as it does not depend upon the mass of species (number of particles) but

∆_{r}

G of the cell reaction is an extensive property because this depends upon the mass of species (number of particles).
