Which of the following cannot form an azeotrope? a) H2O + C2H5OH b) CHCl3 + C2H5OH c) HCl + H2O d) Benzene + Toluene

Which of the following cannot form an azeotrope?

a) H2O + C2H5OH

b) CHCl3 + C2H5OH

c) HCl + H2O

d) Benzene + Toluene

Solutions

Expert Solution

Answer : d) Benzene + Toluene

Explanation :

H2O + C2H5OH forms an azeotrope with a boiling point of 351.15 K.

CHCl3 + C2H5OH forms an azeotrope with a boiling point of 332.3 K.

HCl + H2O forms an azeotrope with a boiling point of 383 K.

Benzene + Toluene is an ideal solution and hence does not form an azeotrope.


d) Benzene + Toluene

Benzene and toluene form nearly ideal solutions. The boiling point of pure benzene is 80.1°C. Calculate the chemical potential of benzene relative to that of pure benzene when xbenzene = 0.30 at its boiling point. If the activity coefficient of benzene in this solution were actually 0.93 rather than 1.00, what would be its vapour pressure?
