Question

Which of the following is incorrect regarding minimum boiling azeotropes?

Answer 1

Minimum Boiling azeotropes:
Minimum boiling azeotropes are those which boil at a lower temperature than boiling point of each component in the pure state. Consequently vapour pressure of the mixture is higher than each component.
Example 95.5 % ethyl alcohol and 4.5 % water by mass forms a minimum boiling azeotrope
Here,

$\Delta H_{mix}>0$
$\Delta V_{mix}>0$
$\Delta S_{mix}>0$
$\Delta G_{mix}<0$
