WebJul 30, 2014 · The first reaction is called a catalytic reduction. Here is a picture of how it works with an olefin like ethylene. You can see that the first step involves adsorption of hydrogen onto the catalyst surface followed by dissociation of the hydrogen molecule into its catalytically active form. The same things happen with nitrobenzene.
