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 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.

The equilibrium constant (K) for the reaction aA + bB ⇌ cC + dD is expressed as K = [C]^c [D]^d / [A]^a [B]^b, where square brackets denote the concentrations of the respective species at equilibrium. The coefficients a, b, c, and d correspond to the stoichiometric coefficients of the reactants and products in the balanced chemical equation. The equilibrium constant provides insight into the extent of the reaction and the relative concentrations of reactants and products at equilibrium.

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.
