These compounds are often written above the arrow in organic (*) chemical reactions.
The effectiveness factor characterizes these substances. They are often ground into tiny pellets and then inserted inside zeo·lites. These compounds are ruined in a process called poisoning. Their phase determines if they are homogeneous or heterogeneous. These compounds are often written above the arrow in organic (*) chemical reactions. These compounds stabilize the transition state more than they stabilize the reactants. Nickel and palladium serve as these compounds in hydrogenations. They lower the energy barrier for a reaction to occur. For 10 points, name these species that aren't consumed or created in a mechanism, and speed up a reaction.
