Chapter 7.3

What the Size of K Tells You, and How K Values Combine

A K of a billion and a K of a billionth describe the same kind of equilibrium, one that lies almost entirely on one side. Reverse the reaction, double it, or chain it to another, and K follows simple rules.

By the end

  1. 01Relate a very large or very small K to the relative amounts at equilibrium
  2. 02Find K for a reversed, scaled, or summed reaction from the K values of its parts
  3. 03Build the equilibrium expression of a multistep process from its steps
