Hint: The minimum pressure which is required to be applied to the solution to prevent the inward flow of the solvent across a semipermeable membrane is known as osmotic pressure. This process is known as osmosis. If there is no osmotic pressure, there will be no movement of solvent. It is a unidirectional process. It tends to make the concentration of solute across the two sides of the membrane equal.
Complete Step by Step Answer:
The symbol for osmotic pressure is pi ($\pi $). The factors on which osmotic pressure depends are the temperature and the concentration of solute. The formula for osmotic pressure is:
$\pi =icRT$; where $i$= van’t hoff index
$c$= Concentration of solute
$R$= Gas constant
$T$= Temperature (Kelvin)
From the formula, we can observe that the osmotic pressure of a dilute solution of a non-volatile solute is directly proportional to its temperature on the kelvin scale.
Correct Option: (C) Directly proportional to its temperature on the kelvin scale
Note: The process of osmosis is important for the human body. In the human body, osmosis occurs in the small and large intestines. It plays an important role in the gastro-intestinal system and kidneys. It helps in getting all the essential nutrients from our food and also removes the waste products from the blood.
