The vapor pressure of a pure liquid was measured at several temperatures and is given in the table below. Vapor Pressure (P, torr) Temperature (T, K) 7.52 353.5 27.73 382.4 62.5 404.0 171.6 434.3 403.3 464.9 736.0 490.0 Create a table of In P and reciprocal temperature in K1. Graph In P vs. 1/T (You may use Excel for this). Use the negative slope of this line (i.e. -m) to determine AHvap, Where AHvap = 8.314 J/molK x (-m). What is AHvap for this liquid? 68.3 kJ/mol 108.3 kJ/mol 28,3 kJ/mol O 48.3 kJ/mol O 88.3 kJ/mol The vapor pressure of a pure liquid was measured at several temperatures and is given in the table below.
