- Direction
- Irreversible
- Processes
- 1
- Stated as
- Stoichiometry only
- Heat of reaction
- ΔH = 1,022,300 kJ/kmol (one process)
- 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.
