Concentration of sodium stearate is increased from 10-5M to 0.0015M then its Osmotic pressure (T is constant)

Osmatic pressure = CRTAs Molarity increases, Osmotic pressure must increasesBut CMC of  sodium stearate is 10-4to 10-3MSo when concentration  increases from 10-5  to 1.5 X 10-3M, it forms Associate micelles.As number of particles decreases, Osmotic pressure decreases
