Medium· Molar Conductivity· +4 / −1
The molar conductivity of 0.007 M0.007\ \mathrm{M} acetic acid is 20 S cm2 mol−120\ \mathrm{S\,cm^2\,mol^{-1}}. What is the dissociation constant of acetic acid ? Choose the correct option. [ΛH+∘=350 S cm2 mol−1, ΛCH3COO−∘=50 S cm2 mol−1]\left[\Lambda^\circ_{\mathrm{H^+}} = 350\ \mathrm{S\,cm^2\,mol^{-1}},\ \Lambda^\circ_{\mathrm{CH_3COO^-}} = 50\ \mathrm{S\,cm^2\,mol^{-1}}\right]
