Question: For the binary mixture of A and B the activity coefficients are given by ln1=Ax22,ln2=Ax12 The vapour pressures of A and B at 80C are

For the binary mixture of A and B the activity coefficients are given by ln1=Ax22,ln2=Ax12 The vapour pressures of A and B at 80C are 119.96kPa and 79.97kPa respectively. Does an azeotrope exist at 80C ? If so, what is the azeotropic composition for A=1 ? Answer: Refer to the same problem description as previously For the binary mixture of A and B the activity coefficients are given by ln1=Ax22,ln2=Ax12 The vapour pressures of A and B at 80C are 119.96kPa and 79.97kPa respectively. Does an azeotrope exist at 80C. If so, what is the azeotropic pressure for A=1 in kPa
