For 10 points, name this quantity, denoted K, which is equal to the ratio of products and reactants of a reaction in stasis.
At a molar ratio of 1, this quantity and enthalpy can be estimated from isothermal titration calorimetry curves. Taking the negative of the slope of a Scatchard plot yields this quantity. This quantity has a much larger value for a porphyrin ring or EDTA compared to their open-chain or monodentate analogs, according to the macrocyclic and chelate effects. The derivative with respect to temperature of the natural log of this quantity is equal to the standard enthalpy change over R T-squared, according to the van 't Hoff equation. There is unusually no denominator in the expression for the "solubility product" form of this quantity. The Henderson–Hasselbalch equation yields the pH as a function of the acid dissociation type of these constants. For 10 points, name this quantity, denoted K, which is equal to the ratio of products and reactants of a reaction in stasis.
