The equivalent conductivity of acetic acid at infinite dilution is $387 \mathrm{S} {\mathrm{cm}}^2 {\mathrm{eq}}^{-1}$. At the same temperature, for $0.001 \mathrm{M}$ solution of acetic acid, it is $55 \mathrm{S} {\mathrm{cm}}^2 {\mathrm{eq}}^{-1}$. What is the degree of dissociation of $0.1 \mathrm{N}$ acetic acid? Assume $1-\mathrm{\alpha }\approx 1$

$$\begin{gathered} \mathrm{A} : 1.5\% \\ \mathrm{B} : 1.35\% \\ \mathrm{C} : 2\% \end{gathered}$$

Enter your correct answer as A, B or C.

The molar conductivity of $0.007 \mathrm{M}$ acetic acid is $20 \mathrm{S}{ \mathrm{cm}}^2{ \mathrm{mol}}^{-1}.$ What is the dissociation constant of acetic acid? Choose the correct option.

$$\begin{gathered} {\mathrm{\lambda }}_{{\mathrm{H}}^{+}}^{\circ }=350 \mathrm{S} {\mathrm{cm}}^2 {\mathrm{mol}}^{-1} \\ {\mathrm{\lambda }}_{{\mathrm{CH}}_3{\mathrm{COO}}^{-}}^{\circ }=50 \mathrm{S} {\mathrm{cm}}^2 {\mathrm{mol}}^{-1} \end{gathered}$$

The molar conductance of $\mathrm{NaCl}, \mathrm{HCl}$ and ${\mathrm{CH}}_3\mathrm{COONa}$ at infinite dilution are $126.45, 426.16$ and $91.0 {\mathrm{Scm}}^2{ \mathrm{mol}}^{-1}$ respectively. The molar conductance of ${\mathrm{CH}}_3\mathrm{COOH}$ at infinite dilution is. Choose the right option for your answer.

The limiting molar conductivity and molar conductivity of acetic acid are $390.5 \mathrm{S} {\mathrm{cm}}^2. {\mathrm{mol}}^{-1}$ and $48.15 \mathrm{S} {\mathrm{cm}}^2. {\mathrm{mol}}^{-1}$ respectively. Calculate the degree acid are of dissociation of the weak acid?
