Vedclass · Answer

(C) The osmotic pressure $(\pi)$ of a solution is given by the formula $\pi = iCRT$,where $i$ is the van't Hoff factor,$C$ is the molar concentration,$R$ is the gas constant,and $T$ is the absolute temperature.From the relation $\pi \propto C$ and $\pi \propto T$,it is clear that the osmotic pressure increases when the concentration $(C)$ of the solution increases,which is directly proportional to the number of solute particles,or when the temperature $(T)$ increases.
