I have a question regarding the simulation of ASPEN applications.
Thread Content
I’m a complete beginner; I’ve just started learning * and have run into difficulties. I hope everyone can offer some guidance. Thank you here! This ASNPEN simulation problem is an example exercise from Chapter 2 of Teacher Sun Lanyi’s tutorial, focusing on the reaction between benzene and propylene to produce isopropylbenzene. In the module for entering reaction data, there is an input value of -1 for the coefficient of benzene, -1 for the coefficient of propylene, and 1 for the coefficient of the resulting isopropylbenzene (as shown in the figure). Why are the coefficients of the reactants -1, while the coefficient of the product is 1? How is this coefficient determined?
The reactants are positive, and the reaction products are negative. You need to study *Physical Chemistry* carefully.
The amount of reactants decreases as the reaction proceeds, while the amount of products increases because they are formed
