Reaction equilibrium constants for

Quantity K is the chemical reaction equilibrium constant for reactionyj and AG° is the corresponding standard Gibbs energy change of reaction (eq. 237). Although called a constant, fC is a function of T, but only of T. 

The equilibrium constants for addition of alcohols to carbonyl compounds to give hemiacetals or hemiketals show the same response to structural features as the hydration reaction. Equilibrium constants for addition of metiianoHb acetaldehyde in both water and chloroform solution are near 0.8 A/ . The comparable value for addition of water is about 0.02 The overall equilibrium constant for formation of the dimethyl acetal of... 

For cases when the concentration of water remains almost constant with respect to the other species, one can define the following reaction equilibrium constants for Eqs. (8.15) and (8.16), respectively ...

Once the chemical reaction equilibrium constant (for a particular reaction) has been determined, one can proceed to estimate the quantities of the participating species at equilibrium. The problem that remains is to relate K to understandable physical quantities. For gas-phase reactions, as in an incinerator operation, the term K may be approximately represented in terms of the partial pressures of the components involved. This functional relationship for the hypothetical reaction... 

Since the normalized advancing front model Is adequate except for small oj values, a legitimate question Is whether oj of 1.0 or less Is likely to occur. Table I shows reaction equilibrium constants for several acidic and basic compounds and concentrations corresponding to oj = 1. Vadues of oj when solute concentrations are 1 ppm are also tabulated. Clearly, removal of trace organic acids or bases with small reaction constants can lead to small a values.

When the reactants release six NH3 molecules in Eq. 1.1, the total number of particles increases from four to seven. This creates entropy and so favors the chelate. Each chelate ring usually leads to an additional factor of about 10 in the equilibrium constant for the reaction. Equilibrium constants for complex formation are usually called/orma-tion constants, the higher the value, the more stable the complex. 

Compare the effect of the reaction equilibrium constant for a heterogeneous reaction with the partition coefficient involved in interfacial transport.
