Question

Assertion and Reason Type:
1. Assertion(A): At STP one mole of any gas occupies 22.4 lit of volume.
Reason (R): 71.0 gm of chlorine gas at STP occupies 2.24 lit of volume.
a) Both A and Rare true and R is the correct explanation of A
b) Both A and R are true and R is not correct explanation of A
c) A is correct and R is incorrect
d) A is incorrect and R is correct​

Answer 1

Explanation:

mole of any gas occupies 22.4 l at STP.

Therefore, 1 mole of O

2

occupies 22.4 l at STP.

Thus the assertion is correct.

The volume of gas depends upon temperature, pressure, no. of moles present but not on the nature of the gas.

Thus the reason is incorrect.
