Although you already know how to calculate equilibrium constant, save yourself some time and make use of our calculator! FAQs What is an equilibrium constant? The equilibrium consta...
Example Equilibrium Constant Calculation For the equilibrium between copper and silver ions: Cu(s) + 2Ag+⇆ Cu2+(aq) + 2Ag(s) The equilibrium constant expression is written as: Kc = [Cu2+] / [Ag+]2 Note the solid copper and silver were omitted from the expression. Also, note the...
Another example of dynamic equilibrium is a ceiling fan rotating with a constant angular velocity.What is Equilibrium? Equilibrium can be defined as the state of an object in which two or more counter-influences, whether internal, external, or a combination of both, act on the body, nullifying...
(for example, H2⇄ 2H), that multiplier appears as an exponent in the calculation ofK(for example,Keq= [H]2/[H2]). When this equation is applied to the ionization of a substance in solution,Keqis called the dissociation constant (Kd) and its negative logarithm (base 10) is the pKd...

For example, Eq. (7) indicates Q when the buffer forms a 1:1 complex with the metal ion, (7)Qbuffer=1+KM-bufferbuffer. If ITC measurements are done in a well-buffered solution, then the concentrations of the acidic and basic forms of the buffer are relatively constant and any coupled...
The calculation of equilibrium constant from the Langmuir model is widely used in the literature. However, the dimensional problem of the equilibrium constant has often been ignored. For example, a recent publication on the strong properties of the new adsorbent for tetracycline. Nevertheless, this ...
Eq. 11) yields an excellent fit versus Rbrew from nonlinear regression, where the best-fit value of equilibrium constant K is 0.717±0.007 with 95% confidence interval over wide range of brewing conditions. This calculation for K assumes that Emax=0.3 is known with perfect confidence; if we ...
