At equilibrium: rateforward = ratereverse
kfwd[N2O4]eq = krev[NO2]2eq
kfwd/krev = [NO2]2eq / N2O4]eq = K
K = the equilibrium constant
The magnitude of K indicates how far a reaction proceeds
toward product at a given temperature.
Example:
(we assume here
that the forward and
reverse reactions are
elementary steps)
