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
`Lambda_m=Lambda_m^oo-bsqrtc`
`260=Lambda_m^oo-0.5 b`...(1)
`260=Lambda_m^oo- b`...(2)
On solving (1) & (2) , we get `Lambda_m^oo=270 Omega^(-1)"cm"^2 "mol"^(-1)`
