Ammonium chromates and some other solids exhibit aging effects. Material that has been stored for months or years follows a cubic law with respect to time, but fresh materials are about fifth-order. At I99°C (390°F), the Front-Tompkins law was followed. 

Pareto, the Italian economist, observed that 85 per cent of wealth is owned by 15 per cent of the population, and it is sometimes stated that 15 per cent of a company s products generate 85 per cent of the turnover. Some workers have interpreted this to mean that 15 per cent of the data will suffice, but Tompkins and White demonstrated that...

Karen Tompkins was Mr. Olian s latest cocktail muse. While her husband switched from Pinot Grigio to a Pinot Noir, Karen tasted a raspberry Flirtini that Mr. Olian set before her and asked her opinion of—a professional Valentine. She liked it.

There have been several papers on Ag oxalate— Ag2C204- Macdonald and Hinshelwood (Ref 7) confirmed the Berthelot equation, according to which the only products of decompn of Ag oxalate are metallic Ag and C02. Benton and Cunningham (Ref 9) found that the rate of thermal decompn of Ag oxalate may be increased by previously exposing it to ultraviolet radiation. During the thermal decompn of Ag oxalate, fragments of metallic Ag are formed. This has been confirmed by conductivity measurements (Ref 10) or by X-ray examination (Ref 11). Tompkins (Ref 1.2) investigated the thermal decompn of Ag oxalate at 110—130°. Its decompn, in his opinion, is similar to that of Ba azide... 

Although the literature contains a very large number of research articles concerned with the kinetics and mechanisms of reactions involving solids, there are comparatively few authoritative, critical and comprehensive reviews of the formidable quantity of information which is available. Probably the most important general account of the field is the book Chemistry of the Solid State, edited by Gamer [63]. Chapters 7—9 are particularly relevant in the present context as they provide a systematic exposition of the kinetic equations applicable to the decomposition of single solids (Jacobs and Tompkins [28]) and their application to endothermic [64] and exothermic [65] reactions.

The systematic treatment of interface advance reactions given by Jacobs and Tompkins [28] remains a valuable survey of the kinetics of solid phase decompositions. A later account was given by Young [29]. Greater mathematical emphasis is to be found in the books by Delmon [30] and by Barret [31]. 

This is known as the Prout—Tompkins equation and has found application to many systems, in addition to the thermal decomposition of potassium permanganate [465] with which it is often associated. The kinetic behaviour of silver permanganate was somewhat different and in a variation of...

Reference to the decomposition of KMn04 has already been made in the discussion of chain branching reactions (Chap. 3, Sect. 3.2) in which the participation of a highly reactive intermediate was postulated. This work provided a theoretical explanation of the Prout—Tompkins rate equation [eqn. (9)]. Isothermal decomposition in vacuum of freshly prepared crystals at 473—498 K gives symmetrical sigmoid a time curves which are described by the expression...
