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
