In chemistry, they can work by adsorption (although there are other methods). This is when the catalyst attaches itself to the reactant particles and then weakens the bond between them, making it easier to react, thus 'lowering the activation energy' (the energy required for a reaction to start).
That is the function of a catalyst.
The function of the catalyst is to stimulate the reaction of H2 with O2 to H2O. At the end of the anaerobic program on the Anoxomat, there is a little overpressure in the jar. After a few minutes the catalyst takes care that the pressure in the jar reduces and that there's no oxygen left.
The spark is the activation energy. It is the catalyst of the chemical reaction.
As most catalysts are quite specific in the (or at least the type of) reaction, in others not working at all, I can't give an answer for 'your acetone-reaction'. But to my best knowledge there are very few reactions I can think of being catalysed by acetone; never heard of, you know.
A catalyst provides an alternative pathway with lower activation energy for a chemical reaction to occur. By lowering the energy barrier, a catalyst speeds up the reaction without being consumed itself. This results in an increase in the rate of the reaction.
A catalyst.
yes
The introduction of new technology served as a catalyst for the company's growth.
Only if there is a desperate housing shortage! More seriously, a catalyst for a desired reaction can function by inhibiting competing reactions.
That is the function of a catalyst.
A catalyst functions to speed up a chemical reaction without being used up in the reaction, meaning that a catalyst can be used more than once.

This substance is called a catalyst.
He serves as a catalyst for the tragic events in the play that follows his death. Such as Romeo's banishment from Verona
