Popis:	bar of H2). However, hydrogen oxidation is not energetically favourable because of the very low acidity of the H-H bond (pKa = 35). This can be dramatically changed through binding of molecular hydrogen to a metal center since the pKa can be lowered by as many as 20 to 30 units, (ref.l, 2). This, in turn, facilitates the heterolytic cleavage
