What is the effect of temperature on the osmotic pressure of solution?...
The correct answer is option D
Osmotic pressure is calculated as:
π = CRT
where, π = Osmotic pressure
C = Concentration
R = Gas constant
T = Temperature.
It is evident from the equation that osmotic pressure is directly proportional to the temperature.

What is the effect of temperature on the osmotic pressure of solution?...
Effect of Temperature on Osmotic Pressure
Osmotic pressure is the pressure required to prevent the flow of solvent molecules through a semipermeable membrane into a solution containing solute molecules. The osmotic pressure is directly proportional to the concentration of the solution and inversely proportional to the volume of the solution. However, temperature also affects the osmotic pressure of a solution.
Increase in Temperature Increases Osmotic Pressure
When the temperature of a solution is increased, the kinetic energy of the solvent and solute molecules increases. This results in an increase in the number of collisions between the solvent and solute molecules. As a result, more solvent molecules pass through the semipermeable membrane into the solution containing solute molecules, increasing the concentration of the solution and thus increasing the osmotic pressure.
This can be explained by the following equation:
Π = CRT
where Π is the osmotic pressure, C is the concentration of the solution, R is the gas constant, and T is the temperature in Kelvin. As the temperature increases, the value of T increases, and thus the osmotic pressure increases.
Therefore, the correct answer is option D - It increases with an increase in temperature.
Conclusion
In conclusion, the osmotic pressure of a solution increases with an increase in temperature due to an increase in the kinetic energy of the molecules, resulting in an increase in the number of collisions between the solvent and solute molecules.
What is the effect of temperature on the osmotic pressure of solution?...
But osmotic pressue is directly proportional to molarity and molarity decrease with increasing temperature what am I right
