Chapter 11, Problem 96E

Interpretation Introduction

Interpretation:

Vapour pressure is pressure exerted by vapour when its pure condensed phase condensed phase (solid orliquoid) is in equilibrium with gas phase (Vapour) vapour pressure is function temper ature for a given pure form vapour pressure of a substance is instrisic property. There are there 1.0L flasks, maintained at 308Kare connected to each other with stop cocks, initially, the stop cock s are closed, there three are opened and missed you have to find out final pressure of mixture. Initially each flaks are maintained at temperature 308K.

In the first flask N₂ is kept at 1 atom.

In the second flask 2.0g of H₂O His kept and in third flask 0.50g of ethanol is kept.

It is given that the vapour pressure of H₂O at 308K is 4233Hg and that of ethanol is 102mmHg.

Concept introduction:

Total pressure inside the flask is summation of pressure due to each component

P_{total> =PN2+PH2O}+P_C2H6o

Ideal gas equation

Pv=nRT
