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
Transcribed Image Text:The image contains two equations related to the natural logarithm of the saturation pressure of components A and B, given in kilopascals (kPa):
1. \( \ln p_A^{\text{sat}} \, (\text{kPa}) = 16.1 - \frac{2900}{T(K) - 40} \)
2. \( \ln p_B^{\text{sat}} \, (\text{kPa}) = 15.9 - \frac{3000}{T(K) - 60} \)
These equations express the natural logarithm of the saturation pressures of two components A and B as functions of temperature in Kelvin (K). The constants and coefficients are specific to each component and are used to model the change in pressure with temperature.
