The following reaction is very important in the formation of smog (O3 is ozone – a severe respiratory irritant):
O2 (g) + NO2 (g) → O3 (g) + NO (g)
At 25°C, Kc for this reaction is 1.67 x 10^-35.
If the concentrations are the following:
[O3] = 1.0 x 10^-8 mole/L
[NO] = 1.0 x 10^-9 mole/L
[O2] = 8.2 x 10^-3 mole/L
[NO2] = 2.5 x 10^-4 mole/L
Show via appropriate calculations whether the reaction is at equilibrium or not. If not at equilibrium, in which direction does the reaction proceed to reach equilibrium?
