Question

Formation of a solution from two components can be considered as
pure solvent → separated solvent molecules, DH1
pure solute → separated solute molecules, DH2
separated solvent and solute molecules → solution DH3
Solution so formed will be ideal if

  1. straight capital delta H subscript text soln.  end text end subscript equals straight capital delta H subscript 1 plus straight capital delta H subscript 2 plus straight capital delta H subscript 3
  2. straight capital delta H subscript text soln.  end text end subscript equals straight capital delta H subscript 1 plus straight capital delta H subscript 2 minus straight capital delta H subscript 3
  3. straight capital delta H subscript text soln.  end text end subscript equals straight capital delta H subscript 1 minus straight capital delta H subscript 2 minus straight capital delta H subscript 3
  4. straight capital delta H subscript text soln.  end text end subscript equals straight capital delta H subscript 3 minus straight capital delta H subscript 1 minus straight capital delta H subscript 2

The correct answer is: straight capital delta H subscript text soln.  end text end subscript equals straight capital delta H subscript 1 plus straight capital delta H subscript 2 plus straight capital delta H subscript 3
