$M g (s) | M g^{2 +} (a q) | | Z n^{2 +} (a q) | Z n (s); E ° = + 3.13 V$
The correct plot of $E_{c e l l}$ versus $\log \frac{[M g^{2 +}]}{[Z n^{2 +}]}$ will be represented as

Options:

Answer:

Solution:

For the given cell,
$E = E^{o} - \frac{0 .059}{2} {log}_{10} \frac{[{Mg}^{2+}]}{[{Zn}^{2+}]}$
This equation is of the form $y = mx + c,$ its slope is negative and intercept equal to $E^{o}$
$S l o p e = - \frac{0.059}{2}$
Intercept $= E^{o}$ .
