InterviewSolution

1.	A flask is partially evecuated to 400 torr pressure of air. A small amount of benzene is introduced into the flask in order that some liwquid will remain after equilibrium has been established. The vapour pressure of at 25^(@)C is 200 torr. What is the total pressure in the flask at equilibrium at 25^(@)C ?
Answer» 120 TORR 510 torr 620 torr 480 torr Solution :Since the temperature `(25^(@)C)` OS constant the total VAPOUR pressure of the equilibrum mixture= 400+220=620 torr.
