the most important thing to know about this is that it just means that the reactants sit on the surface of a catalyst rather than be absorbed, right? is there anything else we should know about adsorption?

I don't think we have to know anything else about heterogenous catalysts and adsorption as Dr. Lavelle said in lecture that we will mainly be looking at homogenous catalysts. We only have to know that heterogenous catalysts act by adsorption and thus by the reactants sitting on the catalyst's surface.

^^^ like they said, most heterogenous catalysts work by simply giving the reactants more surface area to react on. I believe that is all you will need to know about adsorption!
