  • Clark 2013, However, 400–450 °C isn't a low temperature! Rate considerations: The lower the temperature you use, the slower the reaction becomes. A manufacturer is trying to produce as much ammonia as possible per day. It makes no sense to try to achieve an equilibrium mixture which contains a very high proportion of ammonia if it takes several years for the reaction to reach that equilibrium".. Clark, Jim (April 2013) [2002]. "The Haber Process". Retrieved 15 December 2018.
  • Clark 2013, "Rate considerations: Increasing the pressure brings the molecules closer together. In this particular instance, it will increase their chances of hitting and sticking to the surface of the catalyst where they can react. The higher the pressure the better in terms of the rate of a gas reaction. Economic considerations: Very high pressures are expensive to produce on two counts. Extremely strong pipes and containment vessels are needed to withstand the very high pressure. That increases capital costs when the plant is built". Clark, Jim (April 2013) [2002]. "The Haber Process". Retrieved 15 December 2018.
  • Clark 2013, "At each pass of the gases through the reactor, only about 15% of the nitrogen and hydrogen converts to ammonia. (This figure also varies from plant to plant.) By continual recycling of the unreacted nitrogen and hydrogen, the overall conversion is about 98%". Clark, Jim (April 2013) [2002]. "The Haber Process". Retrieved 15 December 2018.
