Q: When a K eq value for an equilibrium is much greater than one, what does it tell you about the position of the equilibrium? A K eq value much greater than one indicates that the equilibrium position favors the formation of products over reactants, suggesting that the reaction proceeds predominantly towards the products. Pure substances in different physical states are in equilibrium; opposite state changes are occurring at the same rate. We compare Q to K to see where the system is relative to equilibrium: Q = K equilibrium; Q < K left of equilibrium (must shift right to reach it) Q > K right of equilibrium (must shift left to reach it) Example.
