When two liquids 'X' and 'Y' are mixed the solution becomes hot. When pair of liquids, 'Y' and 'Z' are mixed, the solution'becomes cold. Which of these SOLUTIONS will exhibit negative deviations from Raoult's law?

Text Solution

Verified by Experts

Solution of .X. and .Y. exhibit negative deviation .r. from Raoult.s law. In this, unlike interaction .X-Y. are much stronger than the like interaction .(X-X. or .Y div Yrangle .. As a result, the heat is evólved.
