2. Explain why a liquid evaporates more readily at higher temperatures by answering the following questions: a. Evaporation is an endothermic process: absorption of heat allows liquid phase molecules to gain enough energy to escape into the gas phase. What is the sign of AHxn? Positive, negative, or 0? b. What is the sign of AS rxn for an evaporation process? You can refer to problem 1 reaction 2, which is the evaporation of N2 from the liquid to the gas phase. c. Use your answers in parts a and b to explain the temperature dependence of AGºrxn and explain why liquid evaporation is favored at higher temperatures.
