Given the following molar conductivities at ${\text{25}}^o\text{C}\text{:, }\text{HCl}\text{, }\text{426 }{\Omega }^{-1}{\text{cm}}^2{\text{mol}}^{-1}\text{; }\text{NaCl, }\text{126}{\Omega }^{-1}{\text{cm}}^2{\text{mol}}^{-1}\text{; }\text{NaC }\left(\text{sodium crotonate}\right)\text{, }\text{83 }{\Omega }^{-1}{\text{cm}}^2{\text{mol}}^{-1}$. What is the ionization constant of crotonic acid? If the conductivity of a 0.001 M crotonic acid solution is $\text{3.83}\times {\text{10}}^{-5}{\Omega }^{-1}{\text{cm}}^{-1}$ ?

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?
