NEET Physics (general) Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): In a mixture of gases, the distribution of molecular speeds remains constant at equilibrium. | Reason (R): Collisions between molecules in the mixture result in a constant change of direction and speed, leading to a Maxwellian distribution.
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
Option A
Detailed Explanation
The NCERT context explains that in a state of equilibrium, the distribution of speeds in a gas mixture remains constant due to continuous molecular collisions, which aligns with the Maxwellian distribution.
