Question

When a non-ideal mixture exhibits a maximum pressure azeotrope at a fixed T: x1 = y1 and x2 = y2 at a pressure above both pure species vapor pressures. y1 > x1 on one side of the azeotrope and x1 > yn on the other side such that the x1-y1 curve crosses the 45-degree line. it will exhibit a minimum temperature azeotrope at a fixed P. all of the above.

Answer 1

(1)At the condition of azeotrope the composition of components are equal in both liquid and vapor phase. So x_{​​​​​1}=y_{​​​​​​1} and x_{​​​​​​2} = y_{​​​​​​2}

(2) for the case of azeotrope the composition of one side is x1>y1 and y1 > x1 on other side.

(3) a maximum pressure azeotrope always exhibit a minimum temperature azeotropeat a fixed pressure.

Here all the statements are satisfied the maximum pressure azeotropic condition . So the correct option is "all of the above".
