Answer:

That the reaction has reached equilibrium..........

Explanation:

And if equilibrium applies to the following reaction:

#A+BrightleftharpoonsC+D#,

then by definition, #k_f[A][B]=k_r[C][D]#

And we can write, #k_r/k_f=K_"equilibrium"=([C][D])/([A][B])#, where #k_r/k_f=K_"equilibrium"# is the thermodynamic equilibrium constant. This must be measured, and has been measured meticulously for many chemical equilibria.
