Ammonium carbamate when heated to 200^(@)C gives a mixture of NH_(3) and CO_(2) vapours with a density of 16.0. What is the degree of dissociation of ammonium carbamate? (Given vapour density of ammonium carbamate is 48)

Answer»

`3//2`
`1//2`
2
1

Solution :`{:(,NH_(2)COONH_(4),rarr,2NH_(3),+,CO_(2)),("Initial","1 MOLE",,,,),("After disso.",1-alpha,,2alpha,,alpha):}`
Total = `1+2alpha`
THEORETICAL, density `(d)prop(1)/((1+2alpha)V)`
`THEREFORE (D)/(d)=1+2alpha`
or, `alpha=(1)/(2)((D-d)/(d))=(1)/(2)((48-16.0)/(16.0))=1.0`
