Question
A solution of two volatile components showing negative deviation from Raoult’s law shows:-
Options :
Decrease in vapour pressure, boiling point increases
Increase in vapour pressure boiling point decreases
Decrease in vapour pressure, boiling point decreases
Increase in vapour pressure boiling point increases
Answer :
Decrease in vapour pressure, boiling point increases
Solution :
In case of negative deviation from Raoult’s law the vapour pressure is less than expected from Raoult’s law and B.P. is more.
