Which liquid has the lowest vapor pressure at 65°C?
2 answers:
Answer: (1) ethanoic acid
Explanation:
- The liquid that has the lowest vapor pressure at 65.0 °C is ethanoic acid.
- As shown in the attached image, the figure in the image shows the relation of vapor pressure with temperature for the mentioned four liquids (ethanoic acid, propanone , ethanol and water).
- Extend a verical line at 65.0 °C and then get the corresponding vapor pressures of the four liquids.
- You will find that the liquid that has the lowest vapor pressure at 65.0 °C is ethanoic acid.
