Solutions Question 6
Question 6 - 2024 (29 Jan Shift 1)
The osmotic pressure of a dilute solution is $7 \times 10^{5} Pa$ at $273 K$. Osmotic pressure of the same solution at $283 K$ is ________ $\times 10^{4} Nm^{-2}$.
Show Answer
Answer (73)
Solution
$\pi=CRT$
$\Rightarrow \frac{\pi _1}{\pi _2}=\frac{T _1}{T _2}$
$\Rightarrow \pi _2=\frac{\pi _1 T _2}{T _1}=\frac{7 \times 10^{5} \times 283}{273}$
$=72.56 \times 10^{4} Nm^{-2}$
