High kinetic

Inorg anic Compounds. Hydrogen chloride reacts with inorganic compounds by either heterolytic or homolytic fission of the H—Cl bond. However, anhydrous HCl has high kinetic barriers to either type of fission and hence, this material is relatively inert. 

The strong shock regime is the classic archetype and is characterized by a single narrow shock front that carries the material from its initial condition into a new high pressure, elevated temperature, high kinetic energy state. Following a quiescent period at peak pressure, whose duration depends upon... 

This situation has some similarities to the chemical change in a spontaneous, exothermic reaction. The reactants of high heat content react spontaneously to form products of lower heat content. As each molecular reaction occurs, the excess heat content becomes kinetic energy. The product molecules separate from each other with high kinetic energy. As they collide with... 

Furthermore, for calculating the effective coefficient of quasi-diffusion in a composite (D) with the corresponding limitation of the entire process of heterogeneous mass-exchange, equations reported in Section 5.1 may be used. The high kinetic permeability of cellosorbents for large organic ions are listed in Table 16. 

So, the active M—C bond in the propagation centers of heterogeneous catalysts is quite stable, its short lifetime being determined by its high kinetic lability as a result of the possibility of various reactions proceeding in the coordination sphere of transition metals. 

It then follows that at low bromine concentrations this latter process is less likely, consequently the kinetic order is reduced. More ionic media will facilitate equilibrium (137) without the need for intervention of equilibrium (139) and vice versa, so that the observed variation in the kinetic order with this condition then follows. The absence of high kinetic orders in molecular chlorination also becomes rationalised since the C1J ion is not as stable as BrJ. 

The nature of the transition state in bromodesilylation is problematical, since the reaction appears to take place in the non-polar solvents benzene and carbon tetrachloride with inversion of configuration at silicon, and, therefore, cannot proceed through a 4-centre intermediate (LVII) as this would lead to retention of configuration746,747. The results are, however, consistent with a six-centre transition state (LVIII), which could follow from the high kinetic order in bromine... 

A heavy body traveling rapidly has a high kinetic energy. A body at rest (stationary, v = 0) has zero kinetic energy. 

The kinetic stability of 17 increases on deprotonation. The half-life times of 17 and its anion N 19 have been estimated [104] from the observed [105, 106] and computed free energy to be only 10 min and 2.2 days, respectively. The high kinetic stability of the anion 19 can be understood in terms of enhanced pentgon stability and aromaticity. The deprotonation raises the energy of lone pair orbitals and promotes cyclic delocalization of o- and rr-electrons. 

Other radioactive atoms decompose by ejecting an electron from the nucleus. These electrons have high kinetic... 

The moderator component of a reactor slows neutrons without capturing them. Moderators are used because the neutrons released in fission have such high kinetic energies that they are difficult to capture. The critical mass of a nuclear fuel is much smaller for slow neutrons than for fast neutrons, so considerably less fuel is needed in a... 

The major impediment to fusion reactions is that the reacting nuclei must have very high kinetic energies to overcome the electrical repulsion between positive particles. The fusion of two hydrogen nuclei has the lowest possible repulsion barrier because it involves two Z — I nuclei. Even so, this reaction requires kinetic energies...
