A compound exists in the gaseous state both as monomer `(A_1)` and dimer `(A_2)`. The molecular weight of the monomer is 48. In an experiment, 96 g of the compound was confined in vessel of volume `33.6L` and heated to `273^(@)C`. Calculate the pressure developed, if the compound exists as a dimer to the extent of 50% by weight under these conditions.

A

`7.5 atm`

B

`2.0 atm`

C

`0.9 atm`

D

`5.4 atm`

Text Solution

Verified by Experts

The correct Answer is:
B
`n_(A)= 1, n_(A_2)= 0.5`
`n= 1.5, V= 33.6 lit, T= 546 K" "therefore P= 2 atm`.
