Question

The osmotic pressure of a solution at $0^{\circ }C$ is 4 atm. Its osmotic pressure at 546 K under similar conditions is?

• A. 5
• B. 6
• C. 7
• D. 8

Answer 1

The correct option is D 8

Let’s look at the following observation.

$\frac{{\pi }_1}{{\pi }_2}=\frac{CR{T}_1}{CR{T}_2}$

$\Rightarrow \frac{{\pi }_1}{{\pi }_2}=\frac{T_1}{T_2}$ (Since we have similar conditions except temperature)

$\Rightarrow \frac{4}{{\pi }_2}=\frac{273}{546}$ (Plugging in the values)

${\pi }_2=8atm$
