The vapor pressure of methanol is 143 mmhg. identify the best reason to explain why methanol spontaneously evaporates in open air at 25.0∘c and standard pressure (760 mmhg). the vapor pressure of methanol is 143 . identify the best reason to explain why methanol spontaneously evaporates in open air at 25.0 and standard pressure (760 ).

Answer/Explanation:

Methanol has a molecular weight (32.04 g/mol), low-boiling point and because of its low boiling point, methanol readily evaporates at room temperature.

Under these specified non-standard conditions, the partial pressure of methanol is lower than its vapor pressure and this explains the reason for the spontaneous evaporation exhibited by methanol.
