What is the relationship between the standard cell potentials $E^{o}$ , for the following two galvanic cell reactions?
(I) $2 A g^{+} (a q) + S n^{2 +} (a q) \to S n^{4 +} (a q) + 2 A g (s)$
(II) $A g (s) + \frac{1}{2} S n^{4 +} (a q) \to \frac{1}{2} S n^{2 +} (a q) + A g^{+} (a q)$

E^{O} (I) = 2 E^{o} (I I)

Solution

The correct option is B $E^{O} (I) = 2 E^{o} (I I)$
The standard cell potential does not depend on the no. of electron transfer taking place $M$ the reaction.
Hence ${E^{0}}_{c e l l}$ is a intensive property.
$∴ E^{0} (I) = E^{0} (I I)$
