Which Statement Concerning the Vapor Pressures of Water and Methanol

question 40

Multiple Choice

Which statement concerning the vapor pressures of water and methanol (CH₃OH) is ?

• A)At 25ºC, methanol has a higher vapor pressure than water because methanol has a lower normal boiling point than water.
• B)At 25ºC, methanol has a higher vapor pressure than water because methanol is a poorer solvent than water.
• C)At 25ºC, methanol has a higher vapor pressure than water because methanol is a less viscous liquid than water.
• D)At 25ºC, methanol has a higher vapor pressure than water because the density of methanol is less than the density of water.
• E)At 25ºC, methanol has a higher vapor pressure than water because methanol has weaker intermolecular forces than water.
