Table 5G.2 in Textbook

[Charlize Choo 1G]

In Table 5G.2 in the textbook, there are values for K and Kc (with a plus next to it). What is the difference between them and why are the values different for some temperatures?

[harshita_ravi_2E]

I'm not too sure about K and Kc but the Kc values at different temperatures because we learned in class that temperature can impact the value of K

[Sophia Tate 1L]

Hi! K is the equilibrium constant when using partial pressures. In this table, all the equations are solely gases, so the usual way to calculate K would be to use the partial pressures. Kc is the equilibrium constant when using concentrations, which is more of what we did in class.

[Payton Zarceno 1E]

HI! In this case, "K" is the equilibrium constant, but "Kc" is the equilibrium constant using concentrations.
