NEET Chemistry (general) Assertion Reason Question
Type: Assertion Reason-assertion-Easy-Class 12
Assertion (A): The vapour pressure of a solution is the sum of the partial pressures of its components. | Reason (R): The partial vapour pressure of each component in a solution is directly proportional to its mole fraction in the solution.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true, but R is false.
D
A is false.
Correct Answer
