And that means our rate of the reverse reaction this way and the rate of the four reaction known this way will be the same. Now, once again, it's important to understand that the concentration of x and Y in equilibrium will not be the same. They could be the same, but it's not necessary for them to be the same. The reason that their rates are equal is because the K constant going this way and the K constant for the reverse reaction are different values. And so the rates are equal even though the concentrations might not be equal because the K's balance the rates out. Now, once again, it's important to understand that entropy at this point is at its highest because entropy defines the most probable state and equilibrium is the most probable state.
