For a mixture of two volatile liquids with the following info, determine the total vapor pressure when the mixture temperature is changed from 279K to 317K if the initial total vapor pressure was 50.Otorr. Compound A: dHvap = 51.7 kJ/mol; Pat initial temp was 52.8torr Compound B: dHvap = 49.8 kJ/mol; p at initial temp was 34.9torr =
