Assertion: Pressure exerted by a mixture...

Assertion: Pressure exerted by a mixture of gases is equal to the sum of their partial pressure.
Reason: Reacting gases react to form a new gas having pressure equal to the sum of both.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion.

B

If both assertion and reason are true but reason is not the correct explanation of the assertion.

C

If assertion is true but reason is false.

D

If the assertion and reason both are false.

Text Solution

Verified by Experts

The correct Answer is:
D
According to Dalton’s law of partial pressure, the pressure exerted by a mixture of non – interacting gases is equal to the sum of their partial pressures (pressure exerted by individual gases in mixture) `P_("total") = P_1 + P_2 + P_3 …..` (T and V constant). Both the gases if non-interacting would spread uniformly to occupy the whole volume of the vessel.
