Manipulating K : Kp for gas rxns
We have been writing K in terms of mol/L.
These are designated by Kc
But with gases, P = (n/V)•RT = conc • RT
P is proportional to concentration, so we can write K in terms of PARTIAL PRESSURES.
These constants are called Kp.
Kc and Kp have DIFFERENT VALUES
(unless same number of species on both sides of equation)
