Given below are two statements; one is labelled as Assertion (A) and the other is labelled as Reason(R). Assertion (A) : Raoult's law is a special case of Henry's law Reason (R) : According to Raoult's law ( P _ i = x _ r p _ 1 ^ ) According to Henry's law ( P = K _ n+1 X ) Here (K_H ) differ from (p₁^ ). In special case (K_H ) becomes equal to (p₁^ ). In the light of the above statements, choose the most appropriate
Options
- ABoth (A) and (R) are correct but (R) is not the correct explanation of (A).
- B(A) is correct but (R) is not correct.
- C(A) is not correct but ( ( R )) is correct.
- DBoth (A) and (R) are correct and (R) is the correct explanation of (A).
Correct answer
C. (A) is not correct but ( ( R )) is correct.
Step-by-step solution
- Assertion (A): "Raoult's law is a special case of Henry's law." This is incorrect because Raoult's law applies to ideal solutions, while Henry's law applies to dilute solutions. - Reason (R): "According to Raoult's law ( Pi = xi pi ^ ); According to Henry's law ( P = KH ) X." This statement correctly describes both laws. The assertion that Henry's law can be adjusted to resemble Raoult's law by setting KH equal to ( pi ^ ) is valid. Thus, while (R) is correct, (A) is not, leading to the conclusion that option (3)
