The base dissociation constant (Kb) is a measure of the strength of a weak base. It is defined as the ratio of the concentrations of the products (BH+ and OH-) to the concentration of the reactant (B) at equilibrium. Mathematically, Kb = [BH+][OH-]/[B].
The acid dissociation constant, denoted as Ka, is the equilibrium constant for the dissociation of an acid into its conjugate base and a hydrogen ion. It is defined as [H+][X-]/[HX], where [H+], [X-], and [HX] represent the molar concentrations of the hydrogen ion, the conjugate base, and the undissociated acid, respectively.
The acid dissociation constant, Ka, is a measure of how well an acid donates a proton in a chemical reaction. For the reaction HX ⇌ H+ + X-, the expression for Ka is [H+][X-]/[HX]. The value of Ka indicates the strength of the acid - higher Ka values indicate stronger acids.
The equilibrium constant for the reaction between Cr(s) and Cu2+ (aq) cannot be determined without knowing the specific reaction equation. The equilibrium constant (K) is a unique value for each specific reaction at a given temperature.
The equilibrium constant for the reaction C + O2 -> CO is Kc = [CO]/([C][O2]), where the square brackets denote molar concentrations.
The equilibrium constant for the reaction SO2(g) + NO2(g) ⇌ SO3(g) + NO(g) is given by the expression Kc = [SO3][NO]/[SO2][NO2], where square brackets denote molar concentrations. The numerical value of this equilibrium constant would depend on the specific conditions of the reaction.

Constant data and constant functions.
dissociation reaction
The concentration of OH- decreases as the concentration of H+ increases. This is beacause there is an equilibrium H2O <-> H+ + OH- and therefore the [H+][OH-] is a constant
A constant is a variable that does not change. The correct term is constant variable.
In neutralisation reactions H+ and OH- ions come from the dissociation of water, H2O, which is part of the solution.Water dissociates in equilibrium, shown as:H2O(l) H+(aq) + OH-(aq)
