Question 11
H

The Haber process is usually run at about 200 atm200\,\mathrm{atm}200atm. A student writes three statements about this choice of pressure.

Statement 1: at 1000 atm1000\,\mathrm{atm}1000atm the equilibrium percentage of ammonia would be higher than at 200 atm200\,\mathrm{atm}200atm

Statement 2: 200 atm200\,\mathrm{atm}200atm is used because equilibrium would be reached more slowly at 1000 atm1000\,\mathrm{atm}1000atm

Statement 3: higher pressures are avoided mainly because of the cost and safety of the equipment needed
