Please choose the correct ending to complete the given sentence: Education and Communications: [header] How to study the use of catalysts in chemistry [title] Define the process. [step] Catalysis of chemical reactions refers to a process in which an external chemical agent is used in order to speed up a chemical process which is typically a chemical transformation or a chemical reaction. Catalysts that are known in the chemical literature are of several types.

Ending1: These will include : [substeps] Aquariums which learn the process of creating, representing, and storing a chemical. Chambers which can learn the process of storing and storing a chemical at the beginning and then using it again the process usually takes between ten and seven days to correct. Ending2: The more catalysis of a chemical to make further changes in reaction techniques, the more likely the test result is to be accurate. Before proceeding, the most important thing is to work out what the two chemical reactions are. Ending3: All of them have the same role and purpose which is the acceleration of chemical processes. Chemical catalysts usually enhance the rate of chemical reactions by lowering its energy barrier or activation energy of the chemical reaction. Ending4: [substeps] Catalysts you study possess large accelerators, injected (hopefully through their ability to release substantial converted ions), molecules that undergo a process, and reactions that can be injected into their respective respective containers. A chemistry study that uses catalysts each time it happens has its starting point.
