Haber Process ?? Yahoo Answers

· High pressure is important (usually around or above 200 atm, more important than high temperature) to increase reaction rate, though a high enough temperature must also be used for the catalyst to be efficient (at least 400 degrees Celcius). The most common catalyst for the Haber reaction is iron, though osmium and uranium were used Uranium hexafluoride Uranium hexafluoride (U F 6), referred to as "hex" in the nuclear industry, is a compound used in the uranium enrichment process that produces fuel for nuclear reactors and nuclear weapons. what is haber process?
