The equivalent conductances of NACl at concentration c and at infinite dilution are `lambda_(c)` and `lambda_(oo)` respectively. The correct relationship between `lambda_(c)` and `lambda_(oo)` is given as : (where the constant b si positive)

A

`lambda_(c)=lambda_(oo)-b sqrt(c)`

B

`lambda_(c)=lambda_(oo)+bsqrt(c)`

C

`lambda_(c)=lambda_(oo)+bc`

D

`lambda_(c)=lambda_(oo)-bc`

Text Solution

Verified by Experts

The correct Answer is:
A
According to Debye-Huckel relation :
`lambda_(c)=lambda_(oo)-b sqrt(c)`
