Question 1
and are two volatile liquids with molar weights of and respectively. Two cotton plugs, one soaked in and the other soaked in , are simultaneously placed at the ends of a tube of length cm, as shown in the figure. The tube is filled with an inert gas at 1 atm pressure and a temperature of . Vapours of and react to form a product whichh is first observed at a distance cm from the plug soaked in .
Take and to have equal molecular diameters and assume ideal behaviour for the inert gas and two vapours.
The experimental value of is found to be smaller than the estimate obtained using Graham's law. This is due to
