### Thermodynamics and Physical Chemistry Problems

#### Problem 1
Using Lee/Kesler Generalized Correlation Tables, calculate the fugacity of compound A at 25.5°C and 107.5 bar. Data for compound A is given below:

- **Critical Temperature (Tc):** 373.5 K
- **Critical Pressure (Pc):** 89.63 bar
- **Acentric Factor (ω):** 0.094
- **Molecular Weight (MW):** 34
- **Density of liquid at 25.5°C (ρ liquid):** 611.25 kg/m³
- **Density of vapor at 25.5°C (ρ vapor):** 1.434 kg/m³ 
- **Saturation Pressure at 25.5°C (Psat):** 18 bar

#### Problem 2
The following equation of state (EOS) is proposed to account for deviations from ideal gas behavior:

\[ \frac{RT}{V_m - b} - a = P \]
