Type: MCQ-numerical-Medium-Class 12

The plot of osmotic pressure (Π) vs concentration (mol L⁻¹) for a solution gives a straight line with slope 25.73 L bar mol⁻¹. The temperature at which the osmotic pressure measurement is done is: (Use R = 0.083 L bar mol⁻¹ K⁻¹)

A

25.73°C

B

12.05°C

C

37°C

D

310°C

Correct Answer

Option C

Detailed Explanation

The slope of the line in an osmotic pressure vs concentration plot is given by RT. Solving for T gives approximately 310 K, which is 37°C.
