Question

$\mathrm{Standard}\mathrm{potential}\mathrm{of}\mathrm{two}\mathrm{half}\mathrm{cell}{E}_1^0\mathrm{and}{E}_2^0\mathrm{can}\mathrm{not}\mathrm{be}\mathrm{added}\mathrm{directly}\mathrm{because}\mathrm{they}\mathrm{are}$.

• A. intensive properties
• B. extensive properties
• C. non- directional

Answer 1

The correct option is A intensive properties

Stanadrad electrode potentials are intensive propertie which means that they cannot be added, just like when two solutions are mixed their densitites cannot be added to get their final density.
When two half cells are combined, we still add the $\Delta G$ values which make it seem like we are adding the
$E^{\circ }$ values.
