Hello! To begin to ask for excuses you for my English poor level... I am a Spanish student of Chemical Engineering. Now I am employed at the simulation of a series of chemical reactions with Mathematica.
As soon as I have programmed the problem to resolving, 23 equations with 23 variables, I use the function Nsolve to solve it, but the program returns to me neither anything, nor message of any mistake, remains for a long time in "running" until I close the program.
Might someone help? I attach the file, for if someone could solve my doubt.
Thank you very much!
