Vedclass · Answer

(D) According to the thermodynamic relationship between Raoult's law and Henry's law,if one component of a binary solution obeys Raoult's law $(P_i = x_i P_i^o)$ over the entire range of composition,the other component must also obey Raoult's law.However,in dilute solutions,the solvent obeys Raoult's law $(P_1 = x_1 P_1^o)$ while the solute obeys Henry's law $(P_2 = K_H x_2)$.The Assertion is incorrect because if one component obeys Raoult's law,the other component often obeys Henry's law in the dilute range.The Reason is correct because Raoult's law is indeed a special case of Henry's law where the Henry's constant $(K_H)$ becomes equal to the pure component vapor pressure $(P_i^o)$.

Assertion : If one component of a solution obeys Raoult's law over a certain range of composition,the other component will not obey Henry's law in that range.
Reason : Raoult's law is a special case of Henry's law.
