The equation, including the catalyst for the hydration of 1-methylcyclobutene is: C5H8 + H2O + HX ---> C5H8OH + H2O.
CuCO3 ==> CO2 + CuO (heat is the catalyst, written above the arrow)
You mean in a chemical equation? There it is always written over the arrow. Like so: .........electricity 2H2O------------>H2+O2
Promoter is a chemical substance used to increase the efficiency of a catalyst used in a chemical reaction, although it may not be a catalyst for the reaction.
You write the name over the arrow in the chemical equation.
A chemical formula written over the arrow in a chemical equation is that of the catalyst used in the reaction.

It means you have some manganese(IV) oxide. This compound most often shows up in chemical equations as a catalyst. It is most popularly used as a catalyst in the decomposition of hydrogen peroxide (H2O2.) A catalyst speeds up a chemical reaction by lowering the reaction's activation energy. In the equation for a chemical reaction, the catalyst is written in superscript-small symbols above the "yield" arrow.
The enzyme is written above the arrow of the chemical equation because it is involved in the reaction without being changed by it or used up in the reaction. It is not a reactant or a product.
