$\Lambda_m$ decreases with an increase in concentration.

Vedclass · Answer

(B) Molar conductivity $(\Lambda_m)$ is defined as the conducting power of all the ions produced by dissolving one mole of an electrolyte in a solution of volume $V$. As the concentration of the solution increases,the number of ions per unit volume increases,but the volume of the solution containing one mole of electrolyte decreases. Due to the decrease in volume and increased inter-ionic attractions at higher concentrations,the mobility of ions decreases. Consequently,the molar conductivity $(\Lambda_m)$ decreases with an increase in the concentration of the solution.

What is the relation between the concentration of solution and molar conductivity $(\Lambda_m)$?
