Chemistry Question on Solutions
A solution of two liquids boils at a temperature more than the boiling point of either of them. Hence, the binary solution shows
A
negative deviation from Raoult's law
B
positive deviation from Raoult's law
C
no deviation from Raoult's law
D
positive or negative deviation from Raoult's law depending upon the composition
Answer
negative deviation from Raoult's law
Explanation
Solution
Solutions boils at relatively higher temperature, vapour pressure of solution is less. Hence, it shows negative deviation from Raoult's law.
