The variation of vapour pressure (b) as a function of temperature (a) is studied for C2H5OC2H5,CCl4, and H2O at 760mm Hg and is shown in the figure below. The boiling temperature of C2H5OC2H5,CCl4, and H2O are 308,350 and 373K respectively. Curves A,B, C respectively correspond to:
A liquid enclosed in 1.0L flask at 298K. The vapour pressure exerted by the liquid is 20.0 mm. when the same liquid is enclosed in a flask of 5L capacity at the same temperature, the vapour pressure of the liquid will be:
