On lowering of temperature of solution, the rate of osmosis decreases ...
Explanation:
When the temperature of a solution is lowered, the rate of osmosis decreases. This can be explained by the following reasons:
1. Decrease in kinetic energy:
The decrease in temperature leads to a decrease in the kinetic energy of the solvent molecules. As a result, the velocity of the solvent particles decreases, which in turn reduces the rate of osmosis.
2. Changes in solute behavior:
Lowering the temperature can cause the solute to undergo either dissociation or association. This can lead to changes in the concentration of solute particles in the solution and affect the rate of osmosis.
3. Decrease in rate of transfer:
The rate of transfer of particles across a semi-permeable membrane decreases with a decrease in temperature. This is because the movement of particles across the membrane is driven by the concentration gradient, and a decrease in temperature reduces the concentration gradient.
4. Increase in viscosity:
Lowering the temperature can increase the viscosity of the solvent. This can make it difficult for the solvent particles to move across the membrane, resulting in a decrease in the rate of osmosis.
Conclusion:
The decrease in the rate of osmosis with a decrease in temperature can be attributed to the decrease in the kinetic energy of the solvent molecules, changes in the behavior of the solute, decrease in the rate of transfer of particles across the membrane, and an increase in the viscosity of the solvent.
