![**Vapor Pressures of Benzene and Toluene**
The vapor pressures of benzene and toluene can be modeled by the expressions:
\[
\ln\left(\frac{P_{\text{benzene}}^*}{1 \text{ bar}}\right) = 10.931 - \frac{3856.6 \, K}{T}
\]
\[
\ln\left(\frac{P_{\text{toluene}}^*}{1 \text{ bar}}\right) = 11.777 - \frac{4514.6 \, K}{T}
\]
These equations are applicable between the temperatures of 353 and 385 K, where the pressure is given in bars and \( T \) in K.
**Instructions:**
Assuming that benzene and toluene form an ideal solution in all proportions, construct a temperature-composition diagram of this system at an ambient pressure of 775 torr. (Note: 760 torr = 1 atm.)
**Task Details:**
(a) Report the mole fraction of benzene in the liquid and vapor phases at \( T = 375 \, K \).
(b) Report the mole fraction of toluene in the liquid and vapor phases at \( T = 360 \, K \).
**Additional Requirement:**
You should include a copy of your diagram with your submitted work on the problem set.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F3c924432-5356-4d2a-9799-f03f3a53c4ab%2Fea33f86a-9003-4612-836f-1f5f8311f89b%2Fggvbswa_processed.png&w=3840&q=75)
