A cumulative or overall constant, given the symbol β, is the constant for the formation of a complex from reagents. For example, the cumulative constant for the formation of ML 2 is given by M + 2 L ⇌ ML 2; [ML 2] = β 12 [M][L] 2. The stepwise constant, K, for the formation of the same complex from ML and L is given by
In general, solving these nonlinear equations presents a formidable challenge because of the huge range over which the free concentrations may vary. At the beginning, values for the free concentrations must be estimated. Then, these values are refined, usually by means of Newton–Raphson iterations. The logarithms of the free concentrations ...
The Van 't Hoff equation relates the change in the equilibrium constant, K eq, of a chemical reaction to the change in temperature, T, given the standard enthalpy change, Δ r H ⊖, for the process. The subscript r {\displaystyle r} means "reaction" and the superscript ⊖ {\displaystyle \ominus } means "standard".
The KP equation was first written in 1970 by Soviet physicists Boris B. Kadomtsev (1928–1998) and Vladimir I. Petviashvili (1936–1993); it came as a natural generalization of the KdV equation (derived by Korteweg and De Vries in 1895). Whereas in the KdV equation waves are strictly one-dimensional, in the KP equation this restriction is ...
A new trend gaining popularity among people trying to lose weight is microdosing the diabetes medication Ozempic. Experts weigh the pros and cons of the practice.
A 29-year-old man’s debilitating night terrors were the first sign of rare autoimmune disorder that rapidly progressed, landing him in the intensive care unit in a “catatonic state.” Ben ...
For any given n, the associated states are called a band. In each band, there will be a relation between the wavevector k and the energy of the state E n , k , called the band dispersion . Calculating this dispersion is one of the primary applications of k · p perturbation theory.
