Question

Assertion:PV/T=constant for 1 mole of gas. This constant is same for all gases.

Reason:1 mole of different gases at NTP occupy same volume of 22.4 litres.


  1. Both assertion (A) and reason (R) are correct and R gives the correct explanation
  2. Both assertion (A) and reason (R) are correct but R doesnt give the correct explanation
  3. A is true but R is false
  4. A is false but R is true

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

Solution
Verified by Toppr

For 1 mole
PV/T=R
and universal gas constant R is constant for every gas
therefore 1 mole of gas at NTP will also occupie 22.4 L of volume
Assertion is true reason is true
and reason is correct explaination
option(A)
