Question

how does the enthalpy change during the formation of a non ideal solution two liquids showing positive deviation from Raoult's law​

Answer 1

Answer:

The enthalpy of mixing is positive that is, Δmix H > 0 because the heat absorbed to form new molecular interaction is less than the heat released on breaking of original molecular interaction. The volume of mixing is positive that is, Δmix V > 0 as the volume expands on the dissolution of components A and B.
