Can you use sound of any frequency or amplitude for example to induce a chemical reaction?

generally they energy per molecule is pretty small compared to the overall motion of the molecules.

 

sound can be used to agitate a mixture of reactants that would increase the rate of reaction.

 

and then there is sound providing a trigger for a reaction (like a very sensitive explosive) the sound initially speeds up the decomposition of the compound until it is enough to sustain a runaway chain reaction.

 

it could maybe also be used in separation methods.

 

thats about all i can think of.

 

in general, no. in a few specific cases, yes.

Yes, it's called sonochemistry.

you always know you've missed a big one. yeah, google sonochemistry and you'll get a bunch of examples.
