Temperature Dependence of AGm and In

From Equation (10.22), when applied to a reaction in solution, we use K, not Kp 

Such behavior is exhibited by the simple chemical reaction 

Very precise, classic, measurements of the ionization constant of acetic acid were made many decades ago [2]. The dependence of In K on temperature is illustrated in Eigure 10.2. As the temperature is increased from 273 K, In K and the degree of ionization increases gradually, reaching a maximum just below 298 K, and then 

When we compare chemical reactions at a fixed temperature, that reaction with the more positive value of AGm is less spontaneous, less capable of progressing from reactants to products. On the other hand, when we compare a given reaction at different temperatures, a temperature with a more positive AGm may show a more
