Reactions and their Reverse Reactions

Postby Justin Bui 2L » Sun Nov 26, 2017 3:11 pm

Can someone explain to me again how the relationship between equilibrium of a reaction and its reverse reaction is inverse?

I will use the example of an equilibrium equation A+B<-->C. The Kc for this forward reaction is Kc=C/A*B. The reverse reaction of this equilibrium system is C<-->A+B. In this reverse reaction, Kc=A*B/C. The two Kc equations have the numerator and the denominator flipped because the reactants and the products of the reaction switch places in the equation itself. Therefore, the Kc for the reverse reaction would be equal to the inverse of the forward reaction, or 1/Kc.
