Chemistry - Ideal Gas Question with Solution | TestHub
Assertion : Most probable velocity is the velocity possessed by maximum fraction of molecules at the same temperature.
Reason : On collision, more and more molecules acquire higher velocity at the same temperature.
Options:
Answer:
Solution:
Assertion is true: Most probable velocity is, by definition, the speed possessed by the maximum fraction of total molecules at a given temperature.
Reason is false: At a constant temperature, the gas system is in a state of dynamic equilibrium, meaning the overall Maxwell-Boltzmann distribution remains completely constant. Individual collisions alter the speeds of specific molecules, but they do not cause more and more molecules to continuously accumulate higher velocities over time.
Therefore, the Assertion is true but the Reason is false, making (C) the correct option.
