MCQ
The Van’t Hoff factor calculated from association data is always...than calculated from dissociation data
  • Less
  • B
    More
  • C
    Same
  • D
    More 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.
