A binary liquid solution is prepared by mixing n-heptane and ethanol. Which one of the following statements is correct regarding the behaviour of the solution ?

Options

A. The solution formed is and ideal solution
B. The solution is non-ideal showing positive deviaation for Raoult's Law.
C. The solution is non-ideal showing nagative deviation form Raoult's Law.
D. n-heptane shows positive deviation while ethanol shows negative deviation rom Rault's Law.

Answer

b

Explanation

In the ethanol and n-heptane mixture, the attrative force will decrease resulting in increase in vapour pressure & thus positive deviation form Raoult's Law.
