At $25^{\circ }\mathrm{C}$, the ${\Lambda }_{\mathrm{m}}{}^{\circ }$ for $\mathrm{HCl},\mathrm{NaCl}$, and ${\mathrm{CH}}_3\mathrm{COONa}$ are 426,126 , and $91\mathrm{S}{\mathrm{cm}}^2{\mathrm{mol}}^{-1}$ respectively. A solution of $0.01\mathrm{M}{\mathrm{CH}}_3\mathrm{COOH}$ has a specific conductance of $1.6\times 10^{-4}\mathrm{S}\mathrm{cm}-1$ at $25^{\circ }\mathrm{C}$. If the solution is heated to $50^{\circ }\mathrm{C}$, the viscosity of water decreases by $30\%$. Estimate the new $\kappa$ (assume $\alpha$ remains constant and ions follow Walden's Rule).
