For the following equilibrium, Kc= 6.3 × 1014 at 1000 K
NO (g) + O3 (g) ⇌NO2 (g) + O2 (g)
Both the forward and reverse reactions in the equilibrium are elementary bimolecular reactions. What is Kc, for the reverse reaction?
Equilibrium constant for forward reaction is
Kcfwd =
For reverse reaction, Equilibrium constant is given as,
Kcrev =
= 1/Kcfwd
= 1/6.3×1014
= 1.59 × 10-15
[(Equilibrium constant for reverse reaction) = 1/(equilibrium constant of forward reaction)
i.e, Kcrev = ]
