In a mixture of A and B, components show negative deviation when

A

`DeltaV_(mix) gt 0`

B

`DeltaH_("mix") gt 0`

C

A - B interaction is weaker than A - A and B - B interactions

D

A - B interaction is stronger than A - A and B - B interactions

Text Solution

Verified by Experts

The correct Answer is:
D
A solution containing A and B components shows negative deviation when A - A and B - B interactions are weaker than that of A - B interactions. For such solutions.
`DeltaH = -veand DeltaV = - ve`
