| Assertion: Solutions show deviations from Raoult's law. |
| Reason: The cause for these deviations lies in the nature of interactions at the molecular level. |
A) Assertion and reason both are correct statements and reason is correct explanation for assertion.
B) Assertion and reason both are correct statements but reason is not correct explanation for assertion.
C) Assertion is correct statement but reason is wrong statement.
D) Assertion is wrong statement but reason is correct statement.
Correct Answer: A
Solution :
On mixing two dissimilar substances, their molecular environment changes. Suppose the two components that are mixed to form a non-ideal solution are A and B. When A - B interactions <A - A or B - B interactions, there is a positive deviation from Raoult's law. When A - B interaction >A - A or B - B interactions, there is a negative deviation from Raoult's law.
