Q4 The enthalpy at 390 K and 1.5 bar of binary liquid mixture is H=395 X1+ 560 X2+ X1X2( 35X1+ 12X2) where H is in J/mol. For the stated temperature and pressure, determine : i) Expression of H and H2 in terms of X1, ii) Numerical values for the pure component enthalpies Hand H2 iii) Numerical values for the partial molar enthalpies at infinite dilution OR Assuming raoults law to be valid for system benzeme (1) - ethyl benzene (2). The vapor pressures are given by anotine equations : In p1=14.8858 2888.51/ T-50.41 In p2 = 13.0045 - 3222.47/ T-59.00 Where Pis in kpa and T is in K. Plot P-x-y diagram at 370k
