In the production of quinoline this compound is isolated from the reaction mixture by steam distillation. Calculate (a) at what temperature the mixture of water and quinoline will boil under a pressure of `740,mm Hg`. (b) What is the maximum number of grams of quinoline which can be distilled with `1000g` water vapour under this pressure.
The temperature dependence of vapour pressure.
The temprature dependence of vapour pressure of water and quionoline is given as follows :

Molecular weight of quinoline `=129`

Answer

(a) 98.54`.

Explanation

(a) This is an immiscible mixture of water and quinoline, so
`P_(1)^(@)+P_(2)^(@)=740`
By the help of table, we can say
`=98.5+((99-98.5))/((741.21727.95))xx(740-727.95)=98.54`.
