A compound exists in the gaseous phase both as monomer `(A)` and dimer `(A_(2))` The mol wt of `A` is 48 In an experiment `96g` of compound was confined in a container of volume `33.6` litre and heated to `273^(@)C` Calulate the pressure developed if the compound exists as dimer to the extent of `50%` by weight under samae these conditions .

Answer

2

Explanation

Since `A` and `A_(2)` are two states in gaseous phase having their weight ratio `5%` i.e `1:1`
`:. Mole` of `A = (96xx1)/(2xx48) =1 ( :' n =(w)/(n))`
Mole of `A_(2) = (96 xx1)/(2xx 96) = (1)/(2)`
Total moles of `A` and `A_(2) = 1 + (1)/(2) = (3)/(2)`
`P= (nRT)/(V) = (3xx0.0821 xx 546)/(2xx33.6) =2atm` .
