The presence of Nil impurities slows down the reaction rate
, but with the exception of the compound with 3 phf NR impurity, this retarding effect is significant, but small.
The reaction rate
constant k values tabulated in Table 3 were obtained from the plot of ln([M.
A loop is established within which the amount of vulcanization that takes place during the time increment [DELTA]t, a new temperature of each node at the end of the time increment and a new crosslinking reaction rate
constant are all calculated.
If we assume that the reaction between the adsorbed AA and BD in the liquid phase (Equation (4)) is the rate-controlling step, the overall reaction rate
0 mmol/L), the reaction rate
(A/min) of the calibrator increased, reaching almost the maximum at 5.
The reaction rate
laws derived from the elementary reaction steps in Scheme 1 a and b, respectively, are shown as follows (14):
This implies that the reaction rate
with respect to oxygen concentration is first order.
What's more, the faster reaction rates
lead to fewer undesirable by-products.
8) suggest that the heterogeneous copolymerization of VDF and HFP occurs in two loci, the continuous and the polymer phase, while under some circumstances the reaction rate
can be described by one-locus models (22).
Other researchers, including John Bahcall of the Institute for Advanced Study in Princeton, used earlier data to argue that the proton-nitrogen-14 reaction rate
is slower than the rate that had been assumed.
The rolling-up of this interface leads to a structure with spiral topology and increases the area of mixed fluids, so that diffusion rates, dissipation rates, reaction rate
and combustion rates are very sensitive to this dynamical process.
2 and 3, the reaction rate
constant k and reaction order n can be determined accordingly (Fig.
