... activation energy for the reaction. Chemical kinetics is the study and discussion of chemical reactions with respect to reaction rates, effect of various variables, re-arrangement of atoms, formation of intermediates etc. By the way, the study of motion is called kinetics, from Greek kinesis, meaning movement. At the macroscopic level, we are interested in amounts reacted, formed, and the rates of their formation. At the molecular or microscopic level, the following considerations must also be made in the discussion of chemical reaction mechanism. * Molecules or atoms of reactants must collide with each other in chemical reactions. * The molecules must have sufficient energy (discussed in terms of activation energy) to initiate the reaction. * In some cases, the orientation of the molecules during the collision must also be considered. Chemical kinetics is the study and discussion of chemical reactions with respect to reaction rates and effect of various variables. ...
