Question
If the mixture has an overall molar composition of 45% A and 55% B (binary mixture), find the following:
A. Bubble temperature at 101.3 kPa, analytical solution assuming Raoult’s law
B. Dew temperature at 101.3 kPa, analytical solution assuming Raoult’s law
C. Create a Txy plot and find solutions for part A and B graphically assuming Raoult’s law
 
 
 
 
The image contains equations for calculating the natural logarithm of the saturation vapor pressure for two substances, A and B, measured in kilopascals (kPa).

For substance A:
\[ \ln p_A^{\text{sat}} \, (kPa) = 16.1 - \frac{2900}{T(K) - 40} \]

For substance B:
\[ \ln p_B^{\text{sat}} \, (kPa) = 15.9 - \frac{3000}{T(K) - 60} \]

Where:
- \( p^{\text{sat}} \) is the saturation vapor pressure.
- \( T(K) \) is the temperature in Kelvin.
