NEET2006PhysicsKinetic Theory of GasesActual

Assertion : The root mean square and most probable speeds of the molecules in a gas are the same. Reason : The Maxwell distribution for the speed of molecules in a gas is symmetrical.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of the assertion
  2. BIf both assertion and reason are true but reason is not the correct explanation of the assertion
  3. CIf assertion is true, but reason is false
  4. DBoth assertion and reason are false statements.

Correct answer

D. Both assertion and reason are false statements.

Step-by-step solution

gathered v_ r.m.s = 3 k T m or, 3 R T M v_ probable = 2 k T m or, 2 R T M gathered Assertion is wrong.
