Question

Why the molar conductivity decreases with concentration for surfactant through cmc?

Answer 1

because it been heat upp by the process

Answer 2

$\huge \fbox \red{Answer}$

Molar conductivity increases with a decrease in concentration. This happens because the total volume, V, of the solution containing one mole of electrolyte also increases. Upon dilution, the concentration decreases. ... Variation of molar conductivity with concentration is different for both, strong and weak electrolytes.
