rate constants at equilibrium

Postby katherinemurk 2B » Wed Mar 13, 2019 8:12 pm

When the reaction is at equilibrium, are the rate constants of the forward and reverse equal? In my discussion notes I have
K=1 so k=k' ?

The rate constants of the forward and reverse are not always necessarily equal. Go off of the formula K=k/k'. Since K, in that case, is equal to one, we can say 1=k/k', which is the same as k=k'. However, the equilibrium constant K is not always 1.

K = 1 means that the products and reactants are at equal concentrations at equilibrium. Because this is not always the case, K does not always equal 1 at equilibrium.
