Molar conductivity (L) m of aqueous solution of sodium stearate, which behaves as a strong electrolyte, is recorded at varying concentrations (c) of sodium stearate. Which one of the following plots provides the correct representation of micelle formation in the solution?
(Critical micelle concentration (CMC) is marked with an arrow in the figures)

Options

A.
B.
C.
D.

Explanation

Molar conductivity decreases with concentration till CMC & further decreases rapidly beyond CMC.
