4) Liquids A and B from a non-ideal solution. Consider the following scenarios :

a) (Delta mix H) < 0

b) ( Delta mix H ) > 0

c) ( Dleta mix V ) < 0

d) ( Delta mix V ) > 0

Assign the following explanations to the senarios : 1- Intermoleculare forces between A and B are stronger than between A molecules and between B molecules. 2- Intermolecular forces between A and B are weaker tham between A molecules and B molecules. 3- Molecules B fit in between molecules A ( or vize versa ) better than they do among themselves. 4- Molecules B fit in between molecules A ( or vize versa ) wores than they do among themselves ?

Explanation / Answer

a) (Delta mix H) < 0.................1- Intermoleculare forces between A and B are stronger than between A molecules and between B molecules.(Exothermic process takes place DH= -Ve)

b) ( Delta mix H ) > 0.............2- Intermolecular forces between A and B are weaker tham between A molecules and B molecules. (Endothermic process takes place so DH = +ve)

c) ( Dleta mix V ) < 0........................3- Molecules B fit in between molecules A ( or vize versa ) better than they do among themselves. (volume decreases)

d) ( Delta mix V ) > 0.................4- Molecules B fit in between molecules A ( or vize versa ) wores than they do among themselves (volume increases)

Assign the following explanations to the senarios : 1- Intermoleculare forces between A and B are stronger than between A molecules and between B molecules. 2- Intermolecular forces between A and B are weaker tham between A molecules and B molecules. 3- Molecules B fit in between molecules A ( or vize versa ) better than they do among themselves. 4- Molecules B fit in between molecules A ( or vize versa ) wores than they do among themselves ?
