Irreversible reaction

CH₄N₂O+H₂Ogives2NH₃+CO₂

Direction: Irreversible
Processes: 1
Stated as: Fixed conversion
Element balance: Checked: balances

As the processes state itStoichiometry, conversions, heats of reaction and catalyst windows are taken from each process's files with their provenance. The build checks only that each process's equation balances in every element, from the process's own component formulas; it does not check the numbers. A process's design maturity applies to them.
