Question

Differentiate between positive and negative deviation

Answer 1

If the enthalpy is positive, the reaction is endothermic and adsorbs heat from the environment to occur. If it is negative, it generates heat during the reaction

Answer 2

Positive Deviation- From Raoult's law. In Mixtures showibg A positive deviation from Raoult's Law, The vapour pressure is the mixture is always higher than You would expect from an ideal mixture.

Negative deviation- In This type of deviations, The partial vapour presure of solution is less than that of ideal solution of same composition.
