QAIPMT-2003-Ch-2663: NEET 2003 Chemistry - Class 11 AIPMT-2003-Ch-2663 Solution: Formation of solution from two components can be considered as…

Formation of solution from two components can be considered as (i) Pure solvent →\rightarrow separated solvent molecules, ΔH1\Delta H_1 (ii) Pure solute →\rightarrow separated solute molecules, ΔH2\Delta H_2 (iii) Separated solvent and solute molecules →\rightarrow solution, ΔH3\Delta H_3. Solution so formed will be ideal if

Multiple Choice Options

  • A ΔHsoln=ΔH1+ΔH2+ΔH3\Delta H_{soln}=\Delta H_1+\Delta H_2+\Delta H_3
  • B ΔHsoln=ΔH1+ΔH2−ΔH3\Delta H_{soln}=\Delta H_1+\Delta H_2-\Delta H_3
  • C ΔHsoln=ΔH1−ΔH2−ΔH3\Delta H_{soln}=\Delta H_1-\Delta H_2-\Delta H_3
  • D ΔHsoln=ΔH3−ΔH1−ΔH2\Delta H_{soln}=\Delta H_3-\Delta H_1-\Delta H_2

Step-by-Step Verified Solution

For ideal solution, _ H soln = _ H 1 + _ H 2 + _ H 3
