At 90°c the vapour pressure of l,2·dimethylbenzene is 20kpa and that of 1,3-dimethylbenzene is 18 kpa. w'hat is the composition of the vapour of an equimolar mixture of the two components?

19kPa

Explanation:

the total pressure is given by

The pressure

similarly

for equilibrium process let us consider both have one mole

so

similarly

so

so total pressure=10+9=19 kPa

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
