Use the observation in the first column to answer the question in the second column. C J soft rosoft observation At 45 °C, Substance E has a vapor pressure of 146. torr and Substance F has a vapor pressure of 116. torr. At 1 atm pressure, Substance A boils at -28. °C and Substance B boils at-56. °C. The enthalpy of vaporization of Substance C is smaller than that of Substance D. Explanation Check question Which has a higher enthalpy of vaporization? Substance E Substance F Neither, E and F have the same enthalpy of vaporization. It's impossible to know without more information. Which has a higher vapor pressure? Substance A Substance B Neither, A and B have the same vapor pressure. It's impossible to know without more information. Which has the higher boiling point? Substance C Substance D Neither, C and D have the same boiling point. It's impossible to know without more information. X
