Variation of vapor pressure with temperature can be calculated using Clausius-Clapeyron equation, which assumes that the________________?
Correct answer: A. All A., B. & C.
- A. All A., B. & C.
- B. Molal latent heat of vaporisation is constant within the limited temperature range
- C. Volume in the liquid state is negligible compared with that in the vapor state
- D. Vapor follows the ideal gas law
Explanation
The integrated Clausius-Clapeyron form assumes ideal-gas vapour behaviour, negligible liquid molar volume and nearly constant latent heat over the temperature interval. Therefore all three listed assumptions are included.
