Answer

  1. $\text{E}_{\text{Cell}}$ is an intensive property while $\Delta_\text{r}\text{G}$ of cell reaction is an extensive property.

Explanation:

$\text{E}_{\text{Cell}}$ is an intensive property as it does not depend upon mass of species (number of particles) but $\Delta_\text{r}\text{G}$ of the cell reaction is an extensive property because this depends upon mass of species (number of particles).
