Which Statement Concerning the Vapor Pressures of Water and Methanol

Question 131

Multiple Choice

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


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.
