Redox Reactions And Electrochemistry Ques 724

Question: The resistance of 0.1N acetic acid when measured in a cell with cell constant $ 1.5,c{m^{-1}} $ is $ 5.250,\Omega $ . The value of $ {\lambda_{eq}} $ of $ 0.1,N,AcOH $ is

Options:

A) 60

B) 90

C) 18.4

D) 0.023

Show Answer

Answer:

Correct Answer: A

Solution:

[a] $ {\Lambda_{eq}}=k\times 1000/N $ Now, $ k=1.5/250, $

$ \therefore $ $ {\Lambda_{eq}}=(1.5/250)\times 1000/0.1=60{{\Omega }^{-1}}cm^{2}e{q^{-1}} $
