So, here’s the question which I’m having trouble solving :
Suppose that we condense a gaz mixture. At 25 celsius, what will be the pressure of benzene and of toluene over the obtained liquid.
We know that vapor of pur benzene and pur toluene at 25 celsius are 12,7 kPa and 3,79 kPa respectively. We also previously prepared a solution that has equal molar fraction of benzene and toluene. We had to determine the vapor pression of benzene and toluene. (this is an ideal solution)
This gave us Pbenz=Xbenz * P^o benz= 0.500 * 12.7 kPa = 6,35 kPa
