Figure A3.10.25 Arrhenius plots of CO oxidation by O2 over Rli single crystals and supported Rli/Al203 at PCO = PO2 = 0.01 atm [43]. The dashed line in the figure is the predicted behaviour based on the rate constants for CO and O2 adsorption and desorption on Rli under UHV conditions.

It is also important to develop an understanding of the movement of chemicals through the environment by investigating their fate and behaviour. Based on a chemical s inherent physicochemical properties, it is possible to predict with some degree of certainty which environmental compartment it is likely to reside in and to what extent it is likely to be bioavailable and accumulate through the food chain.

Before describing some of the proposed classifications, it is useful to recognize that experimental investigations have ranged, in depth and purpose, fi om empirical studies, where information has been collected simply to characterize the behaviour of a particular sample heated under a set of conditions as closely related to an industrial-scale process as practicable, to semi-theoretical calculations of expected behaviour based on as few as possible physical properties of the compound (such as bond lengths, lattice energies, crystal structures, etc.). 

Not all reactions show a kinetic behaviour based on a simple order dependence. The most common reason for this is that the reaction is reversible, so the rate will fall as product accumulates, and its concentration will enter the kinetic rate expression. The simplest solution if this happens is to measure initial rates and confine the kinetic study to the first few percent of the reaction. 

In agreement with this, Oosterhuis f showed that even substances which follow Curie s Law down to low temperatures deviate from it when the cooling is sufficiently intense, in a direction such that the susceptibility begins to be independent of temperature he attempted to indicate an explanation of this behaviour based on molecular theory. 

The electrochemical behaviour of stainless steel has not been worked out completely, although the measured data are available. However, one aspect of the behaviour, based on the measured double layer capacity data, seems to be susceptible to interpretation. The capacity-potential curves are determined by the state of the metal surface and by the ionic environment. In this work, it has been assumed that the ionic environment is a constant. This means that the double layer capacity-potential curves should reflect the nature of the metal surface just as, say, an electron energy spectrum in surface science. Stainless steel has a complicated electrochemical behaviour. In previous work [22] an attempt has been made to compare the double layer capacity curves measured during dissolution and passivation of the stainless steel with that of the pure components. It seems that all the data in the high frequency regime can be fitted to eqn. (70) with the Warburg coefficient set equal to zero.

The surfactant affinity difference (SAD) is used to model emulsion phase behaviour based on the chemical potentials of surfactant in aqueous and oil phases. SAD is the negative of the free energy of transfer of a surfactant molecule from an oil to a water phase (see the papers by Salager et al. [132, 142, 143]).

The introduction of behaviour-based safety (BBS) in some of its manifestations threatens to disturb that balance in the same direction by laying the responsibility for accidents too one-sidedly on the workforce. That is an issue of implementation, because BBS is in principle just as applicable to the behaviour of managers as to that of the shop floor workers and could be extended from occupational safety to cover process safety, which would focus on design as well as operations and maintenance. Hopkins (2012) recommends just such an extension in his book on the Deepwater Horizon accident. 

The pseudo-elastic design method may be used for components submitted to intermittent loading, provided that the intervals during which the material is unloaded are suffident to allow virtually complete recovery. Some manufacturers provide recovery data that enable the validity of this assumption to be tested. Altemativefy, the Boltzmann superposition prind-ple may be used to determine whether the assumption gives a satisfactory q>proximatk>n (see Oiapter 4). If not, or if die 1 is varying in a more complex manner, a more complete anafysis of deflection behaviour based upon the Boltzmaim prindple may be necessary. Linearity can be assumed for strains up n> about 0.005.

The above calculated km-dependent rehability characteristics have to be converted into time-dependent. This conversion has to be done to achieve information about the future failure behaviour based on time. After this conversion multiple possibilities using the time dependent reliability characteristics are given such as calculating end of life, serial spare parts or costs of warranty extension.
