Question: Consider the following liquid - vapour equilibrium. $ \text{Liquid }Vapour $ Which of the following relations is correct?
Options:
A) $ \frac{d\ell nG}{dT^{2}}=\frac{\Delta { _{v}}}{RT^{2}} $
B) $ \frac{d\ell nP}{dT}=\frac{-\Delta { _{v}}}{RT} $
C) $ \frac{d\ell nP}{dT^{2}}=\frac{-\Delta { _{v}}}{T^{2}} $
D) $ \frac{d\ell nP}{dT}=\frac{\Delta { _{v}}}{RT^{2}} $
Show Answer
Answer:
Correct Answer: D
Solution:
- Clausius - Clapeyron’s equation $ \frac{d,\ln P}{dT}=\frac{\Delta H _{v}}{RT^{2}} $
