Question:

Write a MATLAB function to calculate the equilibrium solubility of component 1 (x₁) in a binary system at a given temperature and pressure as the input using the fugacity coefficients calculated from the Soave Equation of State (EOS). Your function must:

1. Be user friendly

2. The input of the fitnction should have critical temperature, critical pressure, acentric factor of each component and a given temperature, pressure and a mixing constant kn. (Should be total of 9 inputs)

3. The output is the equilibrium solubility of component 1 (x₁)

4. Use your created function to calculate the equilibrium solubility of CO₂ in n-decane (x₁) at 300 F and 42 bar that k_ij = 0.12 (Knapp et al, p 638). Define component 1 is CO₂ and component 2 is n-decane.
