Talking of big words! ^^
Nothing happens chemically in a Cat' until it passes a certain temperature, aka the 'light off' temp.
Once hot enough, the relationship is, the more 'incompletely-burnt hydrocarbons' that are present in the exhaust gas, the more reactions will occur between NOx, HC and CO; reactions that all give off more heat.
.... at least, that's what the bloke down the pub told me!
