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.

  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).
- vivek shankar on 14 Feb 13
  
  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 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.
