The passage of an electric current through a conducting liquid causes chemical reactions.The resulting effects are called chemical effects of electric current
To provide the required activation energy.
The role of a catalyst is to quicken the chemical reaction . On reacting, it subsequently appears as a product in the next step of the reaction.
The product doesn't exactly provide a role in a chemical reaction, but rather is the result of the chemical reaction occuring. The chemical reaction may occur specifically to produce that product to be used, and it then serves a role in that respect, but generally products don't play a role, but are just the outcome.
The phenomenon which best explains the role of catalyst in a reaction is that the catalyst lowers the Energy of Activation :)
enzyme sped up the chemical reaction
A catalyst is a substance which alters the rate of a chemical reaction but is chemically unchanged at the end of the reaction. basically it increases or decreases the speed of a chemical or biological reaction, but it does not get itself involved in the reaction. hoped this helped (:

energy is released or absorbed.

The chemical reaction is:C6H5NH2 + (CH3CO)2O → C6H5NHCOCH3 + CH3COOH
photosynthesis ------------------------------------------- generically a "photochemical" reaction.
to increase the reaction rate
A catalyst is a chemical species that alters the rate of a chemical reaction without undergoing any type of change. Such catalysts that slow down a reaction are called negative catalysts or poison.
Chemical reaction, a process in which one or more substances, the reactants, of a chemical reaction had a primary role in defining the science of chemistry as it is known today.
