The rate data for respective substrates were fitted to the equation kobs=k1+k2[Nu]. The first-order rate constant, k1, is unaffected by the nature of the nucleophile, whereas the second-order rate constant, k2, increased with increasing nucleophilicity. This was ascribed to the simultaneous ...
SN1reaction follows first-order kinetics, that is, the rate of reaction depends on the concentration of only one reactant, which is tert-butyl bromide and is independent of the concentration of hydroxide ion. Rate $=k\left[\left(\mathrm{CH}_{3}\right)_{3} \mathrm{CBr}\right]$. Hence...
0.5Cu solder balls and the substrates. Three different 18-μm-wide regions were measured in each sample. Then, the areas are divided by the width (18 μm) to calculate the thicknesses. There are three samples for SAC-HEA and SAC-Cu, respectively. The equation can be expressed as ...
The influence of the reactant concentrations, reaction temperature and catalyst amount is investigated. Within the temperature range studied, 303–323 K, the reaction follows the second order kinetic equation -rTEMP = kCTEMPCH2O2, with reaction rate constant k = 2.2 × 107exp (-51200/RT) ...
The rate data for the Menschutkin reaction between strongly activated Z-substituted benzyl p-toluenesulfonates and Y-substituted N,N-dimethylanilines in acetonitrile at 35 °C fit the equation, kobs = k1 + k2 [DMA], which is consistent with concurrent first- and second-orde...
a particular temperature along the reaction path, the resulting rate constants are called kCVT/SCT [17,43,53–56]: kTST/SCT = SCT kTST (20) kCVT/SCT = SCT kCVT (21) The use of Equation (21) is more logical since the reaction path has been calculated to obtain the SCT...
