I don't really understand about catalysts...
I am thinking about an exothermic reaction in the presance of a catalyst.
My understanding was that the catalyst lowers the energy threshold for the reactants to
commence reacting. ( I think that was gotten from shell theory and bonding energys )
My question is... does the catalyst effect the tempature durring the reaction ?
Does the reaction happen at a lower tempature in the presance of a catalyst ?
I am thinking of examples like the catalytic heaters which use propane ... Is that
reaction cooler than an open and maximum tempature burning flame ?
If it IS lower temp... then the question becomes - where did the missing energy go ?
If it is not a lower temp- but the same- then what function is the catalyst serveing ?
Any ideas ?
