Farms need nitrogen-based fertilisers, and they start as ammonia. Run the ammonia plant: hook up nitrogen and hydrogen, pass them over the iron catalyst, cool the mixture so the ammonia liquefies, and recycle the rest. Then take the controls: turn the temperature and pressure and watch the reaction rate, the dynamic equilibrium and your profit change live. Can you find the compromise?
