Kohlrausch's law helps to determine the degree of dissociation of a weak electrolyte at a given concentration.
The molar conductivity`Lambda_m`of .001M acetic acid is` 4.95xx10^(_5)Scm^2mol^(-1)`.Calculate the degree of dissociation`(alpha)`at this concentration if limiting molar conductivity`lamda_m^0`for H+is `340xx10^(-5)Scm^2mol^(-1)`and` CH_3COO^-``50.5xx10^(-5)Scm^2mol^(-1)`

Explanation

`lamda_m^0CHCOOH=4.95XX10^(-5)Scm^2mol^(-1)`
`lamda_m^0CH_3COOH=lamda_m^0CH_3COO^(-)+H^+`` alpha=lamda_m^0/lamda_x10^(-5)m^0=(4.95xx10^(-5))/(390.5xx^(-5))=0.0126`
