Ordering examples

Carrying through the integration as in the preeeding seeond-order example gives Eq. (2-30). 

Well-ordered lamellar structures. The lamellae are arranged in parallel, giving rise to long-range order. Examples are soaps, phosphoUpids and clays. 

However, while in clinical laboratories some 1000 1500 medically relevant measurands are presently examined, the calibration can be made traceable for only about 60 of them to the highest metrological order (examples here include glucose and cholesterol). 

If the primary process is followed by another reaction or if collisions with other molecules are necessary for the reaction, then the reaction rate will depend on concentration. If it depends only on the concentration of the absorbing material the reaction is of the first order, and if it depends on the square of the concentration it is of the second order. Examples of both are known but in photochemical reactions as in thermal reactions the over-all observed reactions frequently appear to follow neither the first nor the second order, usually on account of the existence of two or more reaction steps. Sometimes a. second reaction is slow in getting started because time is necessary to accumulate some of the product of the first reaction. This situation leads to a time-lag or induction period. Again the second reaction may continue after the primary photo-reaction has stopped, giving rise to after-effects.

A constant value of fq shows that the reaction is first-order. Examples 5 ml of ethyl acetate was added to a flask containing 100 ml of 0.1 M HC1 placed in a thermostat maintained at 30 C. 5 ml of the reaction mixture was withdrawn at different intervals of time and after chilling, titrated against a standard alkali. The following data were obtained ... 

Since iq is fairly constant, the reaction is first-order Example The following data are obtained for the hydrolysis of benzene diazonium chloride C6H5N = N - Cl + H20 —> C6H5OH + HC1 + N2(g) ... 

In each subsection, any examples of syntheses that lead directly to pyrazines usually precede any that afford di-, tetra-, or hexahydropyrazines (piperazines) in that order. Examples of any pre-1978 syntheses in each broad category may be located from the cross-references (e.g., H 49) to appropriate subsections in Barlin s parent volume.1686 Less comprehensive reviews of primary syntheses in the pyrazine series have appeared in recent years.743,1287,1426,1677...

However, in kinetic regime D, the variations in the average rate of absorption with the concentration of each component should conform to Eq. (99), and the experimental values measured in equipment where the interfacial area A is known should lead to the values of the partial orders. Examples of such variation in the average volumetric rate of absorption of oxygen

These equations form a system of partial differential equations of the second order. Examples of two complete systems are given in Table 2.1 (a binary mixture and a pure mobile phase or a mobile phase containing only weakly adsorbed additives, a two-component system) and Table 2.2 (a binary mixture and a binary mobile phase with a strongly adsorbed additive, a three-component system). For the sake of simplicity, the equilibrium-dispersive model (see Section 2.2.2) has been used in both cases. The problem of the choice of the isotherm model will be discussed in the next two chapters.
