Question

Formation of a solution from two components
can be considered as
(i) Pure solvent ➝ separated solvent molecules, ΔH₁
(ii) Pure solute ➝ separated solute molecules, ΔH₂
(iii) Separted solvent & solute molecules ➝ Solution, ΔH₃
Solution so formed will be ideal if
(a) ΔH????o???????? =ΔH₃-ΔH₁-ΔH₂
(b) ΔH????o???????? =ΔH₁+ΔH₂+ΔH₃
(c) ΔH????o???????? =ΔH₁+ΔH₂-ΔH₃
(d) ΔH????o???????? =ΔH₁-ΔH₂-ΔH₃

Answer 1

Answer:

Formation of a solution from two components

can be considered as

(i) Pure solvent ➝ separated solvent molecules, ΔH

(ii) Pure solute ➝ separated solute molecules, ΔH₂

(iii) Separted solvent & solute molecules ➝ Solution, ΔH₃

Solution so formed will be ideal if

(a) ΔH????o???????? =ΔH₃-ΔH₁-ΔH₂

(b) ΔH????o???????? =ΔH₁+ΔH₂+ΔH₃

(c) ΔH????o???????? =ΔH₁+ΔH₂-ΔH₃

(d) ΔH????o???????? =ΔH₁-ΔH₂-ΔH₃

Answer 2

Answer :- (c) ΔH????o???????? =ΔH₁+ΔH₂-ΔH₃
