Gibbs Free Energy and equilibrium

Postby Cecilia Jardon 1I » Mon Feb 18, 2019 4:56 pm

In lecture on Friday in the notes it said if G(r) does not equal G(p) then the system (rxn) is not at equilibrium. Can someone explain why that is?

Equilibrium means the forward rate equals the reverse rate. Free energy refers to the amount of energy available to do work. So when the energy of the reactants/products aren't equal, the system is not at equilibrium.

It is also important to note that if deltaG = 0, then the rate of the forward reaction equals the rate of the backwards reaction, meaning that the reaction is at equilibrium.
