Question

Assertion:Maxwell speed distribution graph is symmetric about most probable speed.
Reason: rms speed of ideal gas, depends upon its type (monoatomic, diatomic and polyatomic)

• A. If both assertion and reason are true and reason is the correct explanation of the assertion.
• B. If both assertion and reason are true but reason is not correct explanation of the assertion.
• C. If assertion is true, but reason is false.
• D. If both assertion and reason are false.
• E. If reason is true but assertion is false

Answer 1

Answer: (D)

The speed of o molecule of a gas changes contionusly as a result of collisions with other molecules and with the walls of the containes. Thus, the net result is that we carit speak of the speed of individual molecule. The manner in which the molecules of a gas are destributed oner the speed ranges, from zero to high values, was first investigated by Maxwell using theory of Probability.
