    “…[Image: see text] In simple, reversible, chemical reactions of the type A ⇋ B, chemical equilibrium is related to chemical kinetics via the equality between the equilibrium constant and the ratio of the forward to the reverse rate-constant, i.e., K(eq) = k(f)/k(r), where K(eq) is the equilibrium constant and k(f) and k(r) denote the rate constants for the forward (A → B) and reverse (B → A) reactions, respectively. …”

    “…The corresponding temperature profiles of enthalpy ΔH(T), entropy ΔS(T), and free energy ΔG(T) have thus far been evaluated using a chemical equilibrium two-state model. Taking a different approach, we demonstrated that the temperature profiles of enthalpy ΔH(T), entropy ΔS(T), and free energy ΔG(T) can be obtained directly by a numerical integration of the heat capacity profile C(p)(T). …”

    “…In the absorber column and sulfidic bioreactor, polysulfides (S(x)(2–)) are formed due to the chemical equilibrium between H(2)S and sulfur (S(8)). S(x)(2–) is thought to be the intermediate for SOB to produce sulfur via H(2)S oxidation. …”

    “…The changes of overall protein entropy when individual residues being held rigid support that the rigidity/flexibility equilibrium in protein structure is governed by the La Châtelier’s principle of chemical equilibrium. Key residues of PDZ2 allostery were identified with good agreement with NMR studies of the same protein bound to the same peptide. …”

    “…With the increase in KI concentration, the Raman vibration peak at 160 cm(−1) representing [Formula: see text] ions gradually weakened, while the Raman vibration peak at 110 cm(−1) representing [Formula: see text] ions gradually increased, indicating that the KI in the correcting tank changed the chemical equilibrium of polyiodide ions in PVA. Then abundant chromophore [Formula: see text] ions were consumed and [Formula: see text] ions generated, so that the apparent color of PVA polarizing film gradually changed from dark blue to dark gray, and the chromaticity a-value and b-value gradually increased. …”

    “…Nevertheless, there is evidence that TiBALDH is in equilibrium with TiO(2), and even, the principal structure of the complex has been suggested as [Ti(4)O(4)(lactate)(8)](8−). Since that chemical equilibrium depends on the polarity of the solvent, in this work we explored a diversity of media to test the chemical stability of TiBALDH and its equilibrium with TiO(2) at room temperature. …”
