标题[问题] 一个有关vapor pressure的问题
时间Wed Dec 7 07:28:16 2005
问题如下:
Benzene and toluene form an ideal solution. At 298 K, what is the mole fraction
of benzene in the liquid that is in equilibrium with a vapor that has equal
partial pressures of benzene and toluene? At 298 K, the vapor pressures of
pure benzene and pure toluene are 95 and 28 torr, respectively.
我现在如果设x是mole fraction of benzene 然後1-x 就是mole fraction of toluene
所以Ptotal = (x)(95 torr) + (1-x)(28 torr)
可是我现在不知道Ptotal是多少?
有没有大大可以帮帮我的?
谢谢喔^^

1F：推 sunev:95x=25(1-x) equal parital pressures?? 12/07 07:42
2F：推 AppleAmily:竟然是热力学......囧rz 12/07 10:11
