Assume a benzene–toluene mixture obeys Raoult’s law. Calculate
is the (molar) concentration in the vapor phase,
is the same in the liquid
phase. Specify in each case what type of calculation you are doing.
(c) Give a short reason why or why not Raoult’s law is a good approximation
for this system at these conditions.
You have to find the dependence of saturation pressure versus temperature.
Always cite all your sources.
