Process reverse

All of the reactions leading to the generation of the nitronium ion are summarized in a, processes reversing this generation in b, and all the processes involved in the attack by nitronium ion upon the aromatic and expulsion of the proton in c. [Pg.108]

The energy or power required by any separation process is related more or less directly to its thermodynamic classification. There are, broadly speaking, three general types of continuous separation processes reversible, partially reversible, and irreversible. [Pg.75]

In the neighborhood of every equilibrium state of a thermodynamic system, there exist states unattainable from it by any adiabatic process (reversible or irreversible). [Pg.68]

TdS = dU+PdV This holds good for any process reversible or irreversible, undergone by a closed system, since it is a relationship among properties which are not dependent on path. [Pg.238]

The coefficient actually measures multiple processes (reversible and irreversible adsorption, precipitation, and coprecipitation). Consequently, it is a purely empirical number with no theoretical basis on which to predict adsorption under differing environmental conditions or to give information on the types of bonding mechanisms involved. [Pg.829]

If we wished to be wholly consistent, we could write both reactions as reduction processes. Reversing the direction of reaction (2) means that we need to change the sign of its contribution toward the overall value of AGr, so... [Pg.322]

Incidentally, ICD in DPPC liposomes is observed in the temperature range below Tm but not above. Consequently, the non-linear depression of ICD will be relevant to disordering of DPPC molecular arrangement. The change in ICD is a reversible process. Reverse photoisomerization to the trans isomer restores the initial ICD. [Pg.217]

In confirmation of this assumption, for instance, the binuclear complex [(terpy)(Cl)2Osn(N2)Osn(Cl)2(terpy)] (terpy = 2,2 6, 2 /-terpyr-idine) displays in dmf solution two separate oxidation processes reversible in character 57... [Pg.477]

Adding copper(l) chloride to the molten glass makes the process reversible. When light intensity diminishes, copper ions remove electrons from silver atoms, converting the silver atoms into silver ions. The silver ions then migrate back to the silver chloride crystals. The glass becomes transparent again. [Pg.320]

Scheme 22 (a, b) Amination of the enantiopure alcohols 26a and 24a yields racemic cinnamyl and propargyl amides 27a and 25g. (c) Bismuth-catalyzed C-N bond cleavage makes this process reversible... [Pg.130]

On hydrophilic surfaces, such as PVA or poly(HEMA), OH-groups of the materials are incorporated in the network structure of adsorbed water molecules (see Sect. 4.4). In consequence, the absolute value of Wj(3 — Wi1 is considered to become still smaller, where - owing to the stabilization of water molecules on the hydrophilic surface - the water-removing-process (reverse reaction of Eq. (2.6)) proceeds slowly. Many experiments were carried out with water-adsorbed hydrophilic surfaces, the behavior of which was time-dependent. In a similar way, the water removal from the proteins [Eq. (2.9)] is also considered to proceed slowly. Thus, we must be careful in considering experimental results in comparison with the data in Tables 3, 4 and 5. [Pg.13]

Figure 6.17 also indicates that U = 0.78 V is the highest electrode potential, for which the ORR process is not activated. Conversely, it is the highest potential for which the water dissociation process (reverse of process (28)) is activated. For U > 0.78V water spontaneously dissociates on the Pt surface and blocks surface sites, a process which is likely to be the origin of experimental observations such as changes in Tafel slopes, and a drop in ORR activity [86]. [Pg.428]

ADIABATIC PROCESS. Any thermodynamic process, reversible or irreversible, which takes place in a system without the exchange of heat with the surroundings. When the process is also reversible, it is called isentropic, because, then the entropy of the system remains constant at every step of the process, fin older usage, isentropic processes were called simply adiabatic, or quasistatic adiabatic the distinction between adiabatic and isentropic processes was not always sharply drawn.)... [Pg.34]

As indicated in Sect. 3.2.1.4, it will be assumed that an irreversible process corresponds to/ phe < 0.05 and a reversible one to/ phe > 10. On the basis of these limits, it is clear that the lower the electrode radius, the higher the value of k° needed to consider the process reversible is. For example, for D = 10 5 cm2 s 1, reversible processes are observed in microelectrodes for k° > 10 4// s. This means that for rs = 10 cm a value of k° >0.1 cm s 1 is enough, whereas for rs = 10 5 cm it is necessary for k° > 10 cm s-1. This behavior is in agreement with the enhanced irreversibility observed for microelectrodes, as discussed above. The accuracy of this approach is based on the dependence of the surface concentration of the oxidized species with the reversibility degree. Under these conditions, at... [Pg.161]
