Question

The osmotic pressure of a solution at $0^{o}C$ is 4 atm. What will be its osmotic pressure at 546 K under similar conditions?

• A. 4 atm
• B. 2 atm
• C. 8 atm
• D. 1 atm

Answer 1

Answer: (C)

8 atm

$\frac{{\pi }_1}{{\pi }_2}=\frac{CR{T}_1}{CR{T}_2}$
$\frac{{\pi }_1}{{\pi }_2}=\frac{T_1}{T_2}$
$\frac{4}{{\pi }_2}=\frac{273}{546}$
$\pi =8atm$
