Use the observation in the first column to answer the question in the second column. observation question Which has a higher enthalpy of vaporization? At 85 °C, Substance C has a vapor pressure of Substance C 138. torr and Substance D Substance D has a vapor pressure of 168. torr. Neither, C and D have the same enthalpy of vaporization. It's impossible to know without more information. At any temperature where both substances are liquid, which has the higher vapor pressure? Substance A The enthalpy of vaporization of Substance A is smaller Substance B than that of Substance B. Neither, A and B have the same vapor pressure. It's impossible to know without more information. Which has a higher vapor pressure? At 1 atm pressure, Substance E Substance E boils at 51. °C and Substance F boils at Substance F 63. °С. Neither, E and F have the same vapor pressure. It's impossible to know without more information.
