Put briefly: what effect would the use of a full molar equivalent of catalyst have on a reaction, broadly speaking?

 

One the great advantages of catalysis is that the catalyst only has to be used in a small amount. I'm intrigued as to what effect the use of a full equivalent would have on a reaction - particularly with regard to metal catalysts rather than acid/base or organic catalysts, which would presumably undergo more conventional reactivity at higher concentrations.

more catalyst just means more active sites which allows more reactants to adsorb to the surface and undergo reaction at the same time.

 

this only really makes a difference in continuous processes. batch processes will be sped up by an ever decreasing amount(doubling the catalyst will not reduce reaction times by half)
