In the table, it gives us both the k and kc values for the reactions. What is the difference between the two and how do we know which one to use? For example in problem 5I.13 how do we know whether to use K or Kc when finding the reaction composition?
Typically, you would use Kc when you are given the concentration of the compounds, while Kp when you are working with gases. But in this case, it would not really matter which ones you use to calculate, since the equilibrium ratio would be the same.
In the table I think that K is just referring to Kp based on the fact that all of the equations only have gases. So, use "K" in the table if you are solving using partial pressure and use "Kc" in the table if using concentrations.
