These compounds stabilize the transition state more than they stabilize the reactants.
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.
