- ✓Less
- BMore
- CSame
- DMore or less
✓
Answer
Correct option: A.
Less
a
In case of association of solute particles in solution, the observed molecular weight of solute being more than the normal, the value of factor '$i$' is less than unity (i.e. $i\,<\,1$ ), while for dissociation the value of $i$ is greater than unity (i.e. $i\,>\, 1$), because the observed molecular weight has lesser value than normal molecular weight.
