Abstract
It is generally accepted that the rate determining process in ammonia synthesis is the chemisorption of dinitrogen, at least under the most widely studied process conditions. It is probable that also under these conditions chemisorbed nitrogen atoms are the most abundant surface intermediates. From our recent work it appears that surface iron atoms with a coordination number of 7 are more active than other surface atoms in nitrogen fixation. An explanation of this finding is sought in terms of molecular orbital symmetry and in terms of generally accepted views on the reaction mechanism.
