Statiometery MCQs

Variation of vapor pressure with temperature can be calculated using Clausius-Clapeyron equation, which assumes that the

by
Vapor follows the ideal gas law
Molal latent heat of vaporisation is constant within the limited temperature range
Volume in the liquid state is negligible compared with that in the vapor state
All of the above
✅ The correct answer is option D.

Assuming applicability of ideal gas law, the pure component volume of the vapor in a saturated gas can be calculated from theoretical relationship. The volumetric composition of a vapor saturated gas is independent of the

by
Nature of the liquid
Nature of the gas
Temperature of the liquid
Total pressure
✅ The correct answer is option B.
