The factors determining the rate of reactions between solids are discussed. When the solid phases are internally in equilibrium and when equilibrium also is established at the phase boundaries, the kinetics are given by the geometric dimensions of the system, the free energy decrease, and the ...
Learn about the rate of reaction. Understand the factors affecting the rate of reaction and see how catalyst, concentration, temperature and...
The lifetime of singlet oxygen in supercritical fluid carbon dioxide, under these conditions, extrapolated to the value in the absence of ground state molecular oxygen, was found to be 5.1 ms (at 150 kg/cm2 and 41 °C). The factors determining the lifetime of O2(a1Δg), in ...
Kinetic studies in CH2Cl2 of the displacement of the thioethers from cis-[PtPh2(Et2S)2] with pyridines to yield cis-[PtPh2(py)2] show, in agreement with previous findings, that the rate-determining step is dissociation of a molecule of thioether and the formation of a transient 3-coordina...
At higher concentrations of lectin the rate of agglutination is concentration-independent, indicating that the aggregation reaction is rate-determining. Only 5 to 7% of the 1.2 × 10 5 receptor sites need be occupied by con A in order for agglutination to take place. Although trypsin-treated ...
The relative importance of bond strength, steric effects, and polarity in determining the rate and orientation of free radical subsitution and free radical addition reaction is considered. The factors which control substitution reaction (radical transfer reaction) are gathered together as five "rules",...
shear rate V Adsorption V Permeability reduction V Inaccessible pore volume V Effect of salinity on viscosity and Adsorption V Formation Residual Resistance Factor V Gel Dehydration V In this study, polymer was chemically reacted with cross-linker, and this chemical reaction was coupled within STARS...
Rotaviruses are of great medical significance because they cause gastroenteritis in children. Here the authors provide insights into the mechanism of viral mRNA transcription by determining the in situ cryo-EM structures of a working rotavirus’ RNA-dependent-RNA polymerase, which is of interest for ...
low-rate behaviour to high-rate, power-law decay (transition occurs roughly at\(R_{\mathrm{{T}}} = (1/2)^{1/n}/\tau\)). This meansτis the critical factor determining rate performance. As a result, we would expectτto be related to intrinsic physical properties of the electrode/el...
Bacterial σI factors of the σ70-family are widespread in Bacilli and Clostridia and are involved in the heat shock response, iron metabolism, virulence, and carbohydrate sensing. A multiplicity of σI paralogues in some cellulolytic bacteria have been
