In regard of the following SN2 reaction, what is the rate equation? What is the rate law for this reaction? What factors affect the rate of reaction? What are the units of k in the following rate law? Rate = kXY^{\frac{1}{2 ...
Rate enhancements by cationic surfactants of the SN2 reaction of Cl- with methyl naphthalene-2-sulfonate (MeONs) follow a typical pseudophase model in which the interaction between Cl- and micel-lized surfactant is written as an equation of the Langmuir form with a binding constant, KC1. The...

(A11) Thus, the control equation for outer region can be written as: 1∂ r ∂r r ∂ppm2 ∂r + km2vi ∂ ∂ppm2 km2hi ∂z ∂z = (φct)m2iµgi k f hi (φct) f i+m1iµgi ∂ppm2 αtkm2hi (φct) f i+m1iµgi k f hi ∂(βt) (A12) By using ...
Since, when SN≥SNI, the signal-to-noise ratio in the analog to digital converter governs the total signal-to-noise ratio in the coder, SNI instead of SN is used in the above equation i=(SNI-PG+10.8-20 log10AR)/6. Next, the plurality of successive numbers i-k to i+k are determi...
The relation between a statistically determined experimental response surface model and a physical chemical model based on the Arrhenius equation is analyzed. As a model reaction, first-order ethanolysis of chlorodiphenylmethane (benzhydryl chloride) was used. A Taylor expansion approximation of the integ...

2B). The best fit equation determined three pKa values. The acidic limb is because of an ionizable group with a pKa1 of 8.1 ± 0.1, whereas the basic limb can be accounted for by residues having pKa2 9.2 ± 0.2 and pKa3 9.9 ± 0.4. The pKa3, however, is near or at the highest...
5、D。考察rate equation和halogenoalkane 水解 SN1,SN2机理和有机物命名。因为rate equation是unimolecular所以是SN1,所以反应物应该是tertiary halogenoalkane。 6、B。考察total entropy change表达式。题目已知该反应为exothermic,△H < 0,A错;△Ssurrounding = - △H/ T, △Ssurrounding > 0,B对;反应中 ...
What is the rate law for the following S_N 2 reaction? a) Rate = k(A) b) Rate = k(B) c) Rate = k(A)^2 d) Rate = k(B)^2 e) Rate = k(A)(B) F What, if anything, can be said about the relationship between the coefficients of the balan...
