Yes, volume changes as conversion changes for reactions with varying volumes.

Of course, I'd be happy to help you with your thesis! To find the activity coefficient (γ) for the Methanol - Lauric acid - Methyl Laurate and water system, you can use Aspen Plus. Here's a general outline of how you can approach this: 1. Define the Components: Start by defining the components in your Aspen Plus simulation. Include Methanol, Lauric acid, Methyl Laurate, and Water. 2. Select a Thermodynamic Model: Choose a suitable thermodynamic model for your system. You may consider using the NRTL (Non-Random Two-Liquid) or UNIQUAC model for this purpose, as they are commonly used for systems containing alcohols and organic acids. 3. Set Binary Interaction Parameters: If necessary, set the binary interaction parameters for the selected thermodynamic model. These parameters can be adjusted to match experimental data or literature values for γ. 4. Define the Mixture: Create a mixture in Aspen Plus containing the components of interest. Specify the mole fractions or mass fractions of each component in the mixture. 5. Run the Simulation:Run the Aspen Plus simulation to calculate the activity coefficients for your system at the specified conditions. Make sure to set the temperature range of interest for your γ equation. 6. Analyze the Results:Once the simulation is complete, analyze the results to determine the temperature-dependent equation for γ. You can do this by fitting a curve to the calculated activity coefficients at different temperatures. 7. Validate the Equation: Finally, validate the temperature-dependent equation for γ by comparing the predicted activity coefficients with experimental data or literature values.

@@DrAGP-dn5teThank you for your time. I appreciate your effort to help me! The Aspen plus is not available in my university and we use UniSim, is it okey? And last but not least where i can find thermodynamic data for my system for Unifaq model (Aij , u(m3/mol), and etc)?

You're welcome! Yes, UniSim is a suitable alternative to Aspen Plus for your university projects. As for finding thermodynamic data for the Unifaq model, you can typically find these values in thermodynamic databases or literature sources. Some common sources include the NIST Chemistry WebBook, DIPPR (Design Institute for Physical Properties) database, and various chemical engineering textbooks that cover thermodynamics. Finding thermodynamic data can indeed be challenging and time-consuming. However, conducting experiments in the lab to generate equilibrium data for your system can be a rewarding and valuable endeavor. Consider that generating equilibrium data in the lab for the Methanol - Lauric acid - Methyl Laurate and water system would not only provide you with the necessary thermodynamic data for the Unifaq model but also contribute valuable experimental insights to the field. @@Teik302
