Hello,
In the File attached ' 2NO
2
N
2
O
4
, last table shows K
p
or K
c
?
My answer it is K
c
because K
p
=K
c
*RT
Δn
where R= universal gas constant, T=temperature, Δn= change in number of moles. Isn't it?

They tell you it's K
p
. Admittedly textbooks sometimes have misprints, but why do you think it might not be K
p
?
(Also, you can tell it's K
p
because K = e
-ΔG°/RT
. Why would this not be the case for K
c
?)
