  • better catalyst for the Haber-Bosch process—one that would allow ammonia to be produced at lower temperatures and pressures.

  • "detonated the population explosion," driving the world's population from 1.6 billion in 1900 to 6 billion in 2000.

      Is this largely the result of ammonia being an effective fertilizer?
  • Under high temperatures and very high pressures,

      By Le' Chatelier's Principle, high temperatures and high pressures shift the equilibrium position to the right, and cause more product ammonia to be produced
  • But Haber, a patriotic German Jew, shared some responsibility for those as well: his work helped Germany to significantly prolong WW I, and also to develop the Zyklon B poison gas used in WW II's Holocaust.

      In view of such disastrous consequences of scientific breakthroughs, is our thirst for scientific knowledge (not only pertaining to the Haber Process) a morally sound tendency?

  • Within a few decades, the super- exponential effect on the world's population became obvious (right).

      What a tremendous impact on population! - but can it be solely attributed to the efficient development of large amounts of ammonia through the Haber process?
  • Was the Haber-Bosch process good or bad?
    • vivek shankar
      vivek shankar on 14 Feb 13
       
      Classic TOK question, but again, I don't believe that the Haber-Bosch process alone could have had such an impact. Other scientific developments could be held equally responsible

  • ammonia was sometimes manufactured by the action of steam on calcium cyanamide, called the cyanamide process, which in turn was made by reacting calcium carbide with nitrogen at high temperatures.

      What is the chemical reaction for the cyanamide process?
  • Two types of polymers needed for artificial fibers require the use of ammonia, polyamides (nylon), and acrylics (orlon).
