QUESTION

# What characteristics define a chemical system in equilibrium?

Equality of forward and reverse rates.

For the reaction,

A+BrarrC+D;

there is a forward rate, K_f[A][B]; and a reverse rate, K_r[C][D].

Equilibrium is defined the equality of forward and reverse rates.

i.e. K_f[A][B]=K_r[C][D]

Or, K_f/K_r = ([C][D])/([A][B])

And K_f/K_r = K_(eq), "the equilibrium constant".
