Effect of Temperature on Reaction Equilibrium Constant

The equilibrium constant, K, of a chemical reaction relates to the heat of reaction by 

To express how the reaction equilibrium constant varies with temperature, we separate the variables and integrate  

In many instances, the heat of reaction is essentially constant, and Eq. 5.1.5 

The equilibrium constant, K, relates to the composition of the individual species at equilibrium. For a general chemical reaction of the form bB + cC rR + sS,
