In the laboratory, hexane has been added to nitrobenzene, and vice versa, until completely miscible solutions are obtained. These tests have been carried out at different temperatures, achieving the following results: x(C6H5NO2) 0,14 0,20 0,25 T 273 280 285 x(C6H5NO2) 0,92 0,90 0,85 If you prepare a mixture of 50 g of hexane and 50 g of nitrobenzene at 290K: a) What is the composition and quantity of each phase? b) To what temperature must the mixture be heated to achieve a single phase? c) If you keep heating up from the previous temperature, you can cause the liquid-vapor transition. Qualitatively represents the appearance of this diagram when the enthalpy of the mixing process is zero and negative. 0,08 260 0,95 0,43 293 0,73 0,60 295 0,60
