Question

What is meant by positive and negative
deviations from Raoult's law and how is the
sign of Aso H related to positive and negative
deviations from Raoult's law ?​

Answer 1

Answer:

The solutions which obey Raoult's law over the entire range of concentration are known as ideal solutions. ... If the vapour pressure is higher, then the solution is said to exhibit positive deviation, and if it is lower, then the solution is said to exhibit negative deviation from Raoult's law.
