Calculate the value of `Lambda_(m) ^prop` for `SrCl_(2)` in water at `25^(@)C` from the following data `:`
`{:(Conc. (mol//l t),,0.25,,1),(Lambda_(m)(Omega^(-1)cm^(2)mol^(-1)),,260,,250):}`

A

270

B

260

C

250

D

255

Text Solution

Verified by Experts

The correct Answer is:
A
`^^_(m)=^^_(m)^(infty)-bsqrt(c)`
`260=^^_(m)^(infty)-0.5b` .(1)
`250=^^_(m)^(infty)-b` …(2)
on solving (1) & (2) we get
`^^_(m)^(infty)=270Omega^(-1)cm^(2)mol^(-1)`
