At a certain temperature, 8.00 moles of NO2 (g) are added to a 1 liter container. NO2 (g) reacts with NO (g) and O2 (g).
Reaction: 2 NO2 (g) ⇋ 2 NO (g) + O2 (g)
At equilibrium, the concentration of NO (g) is equal to 2.00 M. Calculate the equilibrium constant Kc.
How do I find Kc here? Without knowing how many moles O2

If you have any query please comment
If you satisfied with the solution please like it thankxx
