The dissociation constant of n-butyric acid is `1.6 xx 10^(-5)` and the molar conductivity at infinite dilution is `380 xx 10^(-4) Sm^(2) mol^(-1)`. The specific conductance of the `0.01M` acid solution is

Options

A. `1.52 xx 10^(-5) Sm^(-1)`
B. `1.52 xx 10^(-2) Sm^(-1)`
C. `1.52 xx 10^(-3) Sm^(-1)`
D. `1.52 xx 10^(-4) S_(m)^(-1)`

Answer

B

Explanation

`alpha=sqrt((K_(a))/(C)),sqrt((K_(a))/(C))=(mu_(alpha))/(mu_(C))`
`mu_(C)=(1000xxK)/(C)`
