Question
Problem 1 The binary system n-hexane (1)+ethanol (2) obeys to the modified Raoult's law with the following activity coefficients expressions: Iny = 1.5 x Inyz = 1.5 x} 1. Show whether or not this system exhibits an azeotrope at 50°C. In case the azeotrope exists, determine its pressure and composition. 2. Over what range of pressure can this system exist as two liquid-vapor phases at 50°C for an overall composition z2 = 0.4?
