Assertion: An ideal solution obeys Raoults Law.
Reason: In an ideal solution, solvent – solvent as well as solute – solute interactions are similar to solute-solvent interactions.

Reason: Diffusion of solvent occurs from a region of high concentration solution to a region of low concentration solution.
