The kinetics equation for pseudo second order reaction
was given by Mckay and Ho and is given below.
Thus, adsorption of Hg(II) ions onto the studied biomasses is assumed to be controlled by a second order reaction
, with an heterogeneous adsorbent surface and different activation energies.
It shows a linear fit for the second order reaction
As seen from these tables, TGA data were fitted for the second order reaction
In addition, the kinetics study for this proposed scheme concluded second order reaction
kinetics for both steps, with much lower activation energies.
The fitting results showed that the reaction kinetics of the nanocomposite system could be described well by the autocatalytic second order reaction
where [k.sub.2] is second order reaction
rate constant, L/mol s; z is stoichiometric coefficient, mol [O.sub.3]/mol [C.sub.i]; and [[C.sub.i]] and [[O.sub.3]] are concentrations, mol/L.
Kinetics studies showed that degradation of RR195 apparently followed second order reaction
"If the formation/attachment reaction is assumed to be a (delete "first order") second order reaction
, the rate of deposit formation, [[??].sub.d] is defined by the following equation:
The kinetic data obtained proved that a second order reaction
can be used to describe TPU polymerization.
[k.sub.2] is the second order reaction
rate constant of phenol oxidation, [m.sup.3] [mol.sup.-1] [s.sup.-1], and [D.sub.ps] is the diffusion coefficient of a phenolic compound in the organic phase, [m.sup.2] [s.sup.-1].
The addition of glutathione to 1- methyl-4-ethynylpridinum triflate 6 with in TES buffer at pH 7 was a second order reaction
(k = 4200 M-1 s-1 at 25 0C).
