Question

Assertion: Real gases do not obey the ideal gas equation.

Reason: In the ideal gas equation, the volume occupied by the molecules as well as the inter molecular forces are ignored.

• A. Both assertion (A) and reason (R) are correct and R gives the correct explanation
• B. Both assertion (A) and reason (R) are correct but R doesnt give the correct explanation
• C. A is true but R is false
• D. A is false but R is true

Answer 1

The correct option is A Both assertion (A) and reason (R) are correct and R gives the correct explanation

The ideal gas law treats the molecules of a gas as point particles with perfectly elastic collisions. This works well for dilute gases in many experimental circumstances. But gas molecules are not point masses, and there are circumstances where the properties of the molecules have an experimentally measurable effect.
