What is the % dissociation of `CH_(3)COOH`, if equivalent conductivity at this dilution and at infinite dilution are 148 and 398 S `cm^(2)//mol` respectivelyA. `37.18%`B. `47%`C. `48.78%`D. `10.8%`

Answer» Correct Answer - A
Degree of dissociation, `alpha`
`=("Equivalent conductance at concentration C")/("Equivalent conductance at infinite dilution")`
`=(148)/(398)=0.3718`
i.e., `CH_(3)COOH` is 37.18% dissociated.
