This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1920 edition. Excerpt: ... molecules of hydrogen chloride formed from one original atom, split from either one of these atoms, is of the order of several thousand; that is, you only need one initial atom split off to set up a reaction which goes spontaneously to combine about four to six thousand. The question occurs to you at once, "Why stop there? Why not go on indefinitely after splitting off one atom?" The answer is very simple, that although the concentration at any time of hydrogen atoms and chlorine atoms is extremely small, you will have some chance of their getting together directly, which would stop the reaction. The reaction would therefore come to an end; soon after you cut off the source of light, so that is why it is necessary to keep up the source of radiant energy. The other means of removing the free atoms besides the straight cross reaction is by some other substance which can react with them to remove them from the field of action, and oxygen is one of those substances. That is where the inhibitors come in. It is well known that a small amount of oxygen inhibits this reaction or will prevent it from starting at all; so we can explain the whole thing without the assumption of any unusual effects not generally recognized by chemists. I do not mean to convey the impression that I do not think unusual effects may not apply in the case of contact catalysis. I hope we will proceed soon to get a solution of that also. We used to think of atoms as little round bullets almost devoid of properties; it was almost impossible to get anywhere in theorizing on the subject of kinetics or catalysts. Now we have learned that the structure of the atom is extremely complex, that the atom is a whole solar system of electrons revolving around the atom, more
