Given below are two statements:
Statement I : The limiting molar conductivity of KCl (strong electrolyte) is higher compared to that of CH3COOH (weak electrolyte)
Statement II : Molar conductivity decreases with decrease in concentration of electrolyte.
In the light of the above statements, choose the most appropriate answer from the options given below:

Statement I is false but Statement II is true
Option 2 -
Both Statement I and Statement II are false
Option 3 -
Both Statement I and Statement II are true
Option 4 -
Statement I is true but Statement II is false.

Correct Option - 2
Detailed Solution:Molar conductivity measured at infinite dilution is called limiting molar conductivity. Hence at infinite dilution stage, both strong electrolyte (KCl) and weak electrolyte (CH3COOH) have identical value of conductivity. Therefore statement – I is false.
Statement – II is also false because molar conductivity increases by the decreasing the concentration of electrolyte.
