Question

The vapor pressure of methanol, CH₃OH, is 94 torr at 20 °C. The vapor pressure of ethanol, C₂H₅OH, is 44 torr at the same temperature.

a) True
b) False

Answer 1

The vapor pressure of methanol, CH₃OH, is 94 torr at 20 °C, and the vapor pressure of ethanol, C₂H₅OH, is 44 torr at the same temperature.

Step-by-step explanation:

The statement is True. The vapor pressure of methanol, CH₃OH, is 94 torr at 20 °C, while the vapor pressure of ethanol, C₂H₅OH, is 44 torr at the same temperature.

The vapor pressure of a liquid is the pressure exerted by its vapor when it is in equilibrium with the liquid phase.

At a given temperature, the vapor pressure of a substance depends on the intermolecular forces between its molecules and the temperature.
