The value of ^^(m)^(infty) for KCl and K...

The value of `^^_(m)^(infty)` for KCl and `KNO_(3)` are `149.86` and `154.96 Omega^(-1) cm^(2) mol^(-1)`
Also `lambda_(Cl^(-))^(infty)` is `71.44 " ohm"^(-1) cm^(2)mol^(-1)` The value of `lambda_(NO_(3)^(-))^(infty)` is

A

76.54 `ohm^(-1) cm^(2) mol^(-1)`

B

`133.08 ohm^(-1) cm^(2) mol^(-1)`

C

`37.7 ohm^(-1) cm^(2) mol^(-1)`

D

Unpredictable

Text Solution

Verified by Experts

The correct Answer is:
A
From `lambda_(Cl^(-))^(infty)` calculate `lambda_(K^(+))^(infty)` and then `lambda_(NO_(3)^(-))^(infty)` by using `lambda_(KNO_(3))^(infty) = lambda_(k+)^(infty) + lambda_(NO_(3)^(-))^(infty)`
