energy released by the reaction or energy absorbed.
The chemical equation is the word expression of a chemical reaction.The rate of reaction give information about the speed of this reaction.
The reactants are the substances that undergo the chemical reaction, and are shown on the left side of a chemical equation. The products are produced by the chemical reaction, and are shown on the right side of the chemical equation.
The amount of heat given off by the reaction
when 2 or more compounds react chemically to form a new compound then it is called chemical reaction chemical reaction whereas the quantity and no. chemical elements presents in chemical compound is called the chemical composition

Catalyst: a substance which promote and help a chemical reaction. Inhibitor: a substance which greatly reduces the rate of a chemical reaction.
a chemical reaction that happens once cannot be reversible while d one with lifewill continue to reproduce
Exothermic reaction is just one of the two possible chemical reactions: either exothermic or endothermic. (No difference but heat release)
