NEET 2024 Chemistry Colligative Properties MCQ Question
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)
25.73°C
12.05°C
37°C
310°C
Correct Answer
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.
