what is the value of equilibrium constant kc?

for example - is the value of Kc is 2, it would mean that the molar concentration of reactants is 1/2 the concentration of products. In this case though the value of Kc is greater than 1, the reactants are still present in considerable amount.

The Ksp expression for a salt is the product of the concentrations of the ions, with each concentration raised to a power equal to the coefficient of that ion in the balanced equation for the solubility equilibrium.

1g KCl = 525 mg of K+ or 13.4 mEq or 13.4 mmol of K+ and Cl- . The dosage of this solution depends on the age, weight, clinical and biological (acid-base balance) conditions of the patient, concomitant therapy and in particular the patient's hydration state.

Also, K=C/Co, where C is capacitance in the presence of dielectric and Co is capacitance when there is vacuum( practically air) between two ' plates' of capacitor. Thus, dielectric constant is ratio of same quantities it is dimensionless number.

So any time the number of gas molecules on the product side is the same as the number of gas molecules on the reactant side, Kc will be equal to Kp.

Kb is the base dissociation constant. The base dissociation constant is a measure of how completely a base dissociates into its component ions in water. Kb = [B+][OH-]/[BOH] pKb = -log Kb.

The Michaelis-Menten equation can then be rewritten as V= Kcat [Enzyme] [S] / (Km + [S]). Kcat is equal to K2, and it measures the number of substrate molecules "turned over" by enzyme per second. The unit of Kcat is in 1/sec.

How can I determine the Kcat of an enzyme? If you plot enzyme velocity as a function of subtrate concentration, you can fit the data to the Michaelis-Menten equation to determine the Km and Vmax. ... It is expressed in the same units you used to enter your Y values (enzyme activity).

Note that x is Related to pH and Calculate Ka As noted above, [H3O+] = 10-pH. Since x = [H3O+] and you know the pH of the solution, you can write x = 10-2.4. It is now possible to find a numerical value for Ka. Ka = (10-2.4)2 /(0.9 - 10-2.4) = 1.8 x 10-5.

Re: Aqueous in Kp? Remember that molar concentration of a pure substance (solid or liquid) does not change in a reaction, thus solids and liquids not included in K expression. So an aqueous solution should be calculated by Kc.

The symbol k is a proportionality constant known as the Coulomb's law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. In the case of air, the value is approximately 9.0 x 109 N • m2 / C2.

In general, the solubility product constant (Ksp), is the equilibrium constant for the solubility equilibrium of a slightly soluble ionic compound. Like all equilibrium constants, the Ksp is temperature dependent, but at a given temperature it remains relatively constant.

The Cl electronegativity is clearly the same so the only variable is the cation. ... Looking at the figures, Cl = 3.16, Na = 0.93 and K = 0.82. As there is clearly a greater electronegativity difference in KCl than NaCl the bond in the former is more ionic in nature.

For any conjugate acid–base pair, KaKb=Kw. Smaller values of pKa correspond to larger acid ionization constants and hence stronger acids. Conversely, smaller values of pKb correspond to larger base ionization constants and hence stronger bases.
