Not illustrated. 1921 Excerpt: ...period of time. For both kinds of reactions, ionic and molecular, it is essential that the ions or molecules come in close contact, for if the two ions or molecules are far apart, they cannot react upon each other. The contact of ions or molecules is usually termed ionic or molecular collision. Any physical means which facilitates ionic or molecular collisions will thus increase the possibility of a reaction taking place. The physical means which increase or decrease the possibility of collisions and so influence a chemical reaction may be of a mechanical, thermal, or electrical nature. Speed of Reaction.--The speed of a reaction is shown in the proportional amount of reaction-products (AD and C.B) which are formed from the reacting substances (AB and CD) in a given period of time. Thus it becomes evident that the control of reactions depends entirely upon the regulation of the speed of the reaction. By application of mechanical, thermal, or electrical means, either alone or in combination, the speed of a reaction is either (a) accelerated (made to proceed faster), (6) retarded (made to proceed slower), (c) stopped (made to stand still), or (d) reversed (made to proceed in the opposite direction). Hence for every reaction there are favorable as well as unfavorable conditions. The Mechanical Control: Surface, Catalyzers, Concentration, and Pressure Frequency of Collisions is Influenced by Number of Molecules Coming in Contact.--The mechanical means which influence the frequency of molecular collisions are those which regulate the number or the amount of molecules. The more molecules collide with each other, the greater the possibility of a reaction, and vice versa. This can be accomplished in four different ways: (1) by increasing the surface of contact betw...
