The standard emf of the cell $\mathrm{Zn}\mid {\mathrm{Zn}}^{2+}\Vert {\mathrm{Ag}}^{+}|\mathrm{Ag}$ is $1.56 \mathrm{V}.$ If the standard reduction potential of $\mathrm{Ag}$ is $0.8 \mathrm{V},$ the standard oxidation potential of $\mathrm{Zn}$ is

In a electrochemical cell, the reaction will be feasible when

The standard electrode potential for Daniel cell is $1.1$ volt. What is the standard Gibbs energy for the reaction?

The molar conductivities of $\mathrm{NaOH},\mathrm{NaCl}$ and ${\mathrm{BaCl}}_2,$ at infinite dilution are $2.481\times {10}^{-2} {\mathrm{Sm}}^2 {\mathrm{mol}}^{-1}1.265\times {10}^{-2} {\mathrm{Sm}}^2 {\mathrm{mol}}^{-1}$ and $2.800\times {10}^{-2} {\mathrm{Sm}}^2 {\mathrm{mol}}^{-1}$ respectively. The molar conductivity of $\mathrm{Ba}{\left(\mathrm{OH}\right)}_2$. at infinite dilution will be

$\lambda °\mathrm{m}$ for ${\mathrm{NH}}_4\mathrm{Cl}, \mathrm{NaOH}$ and $\mathrm{NaCl}$ are $130, 248$ and $126. 5$ ${\mathrm{ohm}}^{-1}{\mathrm{em}}^2{\mathrm{mo}}^{-1}$ respectively. The $\lambda °\mathrm{m}$ ${\mathrm{NH}}_4\mathrm{OH}$ will be,
