Quick steps: • Click “Reaction Selector” to select a pre-defined reaction (or choose your own reactants/products and click "Balance") • Enter the initial composition (molar concentrations or partial pressures). • Enter a temperature (200K-5000K). • Optionally specify reaction rate parameters •
Click “Run the Reaction” to simulate the reaction.
