Comparing two liquid substances at the same temperature, the one with stronger intermolecular forces will: A. c. have a lower vapor pressure because more molecules have enough energy to escape the liquid surface B. have a lower vapor pressure because fewer molecules have enough energy to escape the liquid surface C. have a higher vapor pressure because more molecules have enough energy to escape the liquid surface D. have the same vapor pressure as the other one because they have the same temperature and hence the same average kinetic energy. E. have a higher vapor pressure because fewer molecules have enough energy to escape the liquid surface
