Equilibrium constants have been determined spectrophotometrically for the reaction of cyanide ion with 1,3,5-trinitrobenzene in methanol, ethanol, - and iso-propanol, and - and -butanol. The equilibrium constants at 25 掳C vary from 39 1molefor the reaction in methanol to 500 000 1molewith ...
The equilibrium constants at various temperatures according to Eq. (3) (Table 1), the data in Table 2 [45,46], and the correlations in Eqs. (4) and (5) [40,47] are plotted in Fig. 3. In general, the equilibrium constants correlate well by Eqs. (3) and (4) when the temperatu...

The equilibrium (Ke,l = k1/k-1) and rate constants of the reactions RBr k5k-5 R + Br and Br + RBr k2k-2 R + Br2 (R = R = CH2Cl, CHCl2, CCl3, and CBrF2) at 500-700°C are determined by the method of isothermal pyrolysis of the bromides CH2BrCl, CHBrCl2, CBrCl3, ...
Relations [4.33] suggest the introduction of two new constants C and C′ defined as: [4.34]C≡def(1+c2)+μcs,C′≡def(1+c2)−μcs. Relations [4.33] define a domain of the {α, β} plane, and therefore of the {R1n, R2n} plane. It is easy to see that if μ < (1 + ...
