Plot the chemical equilibrium.

The function plot_chemical_equilibrium plots the main species under thermochemical equilibrium with Cantera.

The function receives the following parameters:

• thermo: Cantera thermo file.

• initial_solution: Initial solution.

• temperatures: Temperatures to evaluate.

• unit: Temperature unit (“K” or “C”).

• keep_only_first_species: Keep only the n first species.

• save_file_name: Save file name.

• fraction: Mole or mass fraction (“mole” or “mass”)
