Question

Assertion :Osmotic pressure of $1M$ glucose is lesser than $1M$ $NaCl\left(aq\right)$ but vapour pressure of $1M$ glucose is higher than $1M$ $NaCl$. Reason: Osmotic pressure is colligative property but vapour pressure is not colligative property however, lowering in V.P. is colligative property.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Assertion is incorrect but Reason is correct

Answer 1

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion

Option (A) is correct.
The osmotic pressure of a solution is proportional to the molar concentration of the solute particles in solution. The osmotic pressure of an ideal solution can be approximated by the Morse equation:

$=iMRT$
