Notes on chemical reactions and equations
Webmany reactions that are written as a single reaction equation in actual fact consist of a series of elementary steps. This will become extremely important as we learn more about the theory of chemical reaction rates. As a general rule, elementary processes involve a transition between two atomic or molecular states separated by a potential barrier. WebEnergy in the form of heat, light or electricity is generally absorbed in these reactions. 🔶 Endothermic Reactions :- The reactions which require energy in the form of heat, light or electricity to break reactants are called endothermic reactions. 🔶 DISPLACEMENT REACTION :- The chemical reaction in which more reactive element displaces ...
