The incorrect statement regarding given information is

Assertion : The molecular weight of acetic acid determined by depression in freezing point method in benzene and water was found to be different.

Reason : Water is polar and benzene is nonpolar.

A solution containing $10 \mathrm{~g}$ of an electrolyte $\mathrm{AB}_2$ in $100 \mathrm{~g}$ of water boils at $100.52^{\circ} \mathrm{C}$. The degree of ionization of the electrolyte $(\alpha)$ is............ $\times 10^{-1}$.

(nearest integer)

[Given : Molar mass of $\mathrm{AB}_2=200 \mathrm{~g} \mathrm{~mol}^{-1} \cdot \mathrm{K}_{\mathrm{b}}$

(molal boiling point elevation const. of water)

$=0.52 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$, boiling point of water $=100^{\circ} \mathrm{C}$;

$\mathrm{AB}_2$ ionises as $\left.\mathrm{AB}_2 \rightarrow \mathrm{A}^{2+}+2 \mathrm{~B}^{-}\right]$

For $Zn - Cu$ cell, $E ^{\circ}=1.10 V$. If the reduction potential $\left[ Cu ^{2+}{ }_{( aq )} / Cu _{( s )}\right]$ pair is 0.34 V , then the reduction potential of $\left[ Zn ^{2+}{ }_{(a q)} / Zn _{( s )}\right]$ pair will be :
