The dissociation constant of n-butyric acid is `1.6 xx 10^(-5)` and the molar conductivity at infinite dilution is `380 xx10^(-4) S m^(2) mol^(-1)` . The specific conductance of the 0.01 M acid solution is

Options

A. `1.52 xxx10^(-5) m^(-1)`
B. `1.52 xx10^(-2) s m^(-1)`
C. `1.52 xx10^(-3) s m^(-1)`
D. `1.52 xx10^(-8) s m^(-1)`

Answer

D

Explanation

Dissociatin constant `2k_(a)=C alpha^(2)`
`1.6xx10^(-5) =0.1 alpha^(2)`
cnducity k =`1.52 xx10^(2) s m^(2) mol^(-1)`
