When there is more product than reactants and the reverse reaction is favored.

Q is calculated using non-equilibrium values. If Q>K, that means that the reaction will proceed to the left, or toward the reactants, to reach equilibrium. The products will be used up to produce more reactants, which in turn will raise the values for the reactants and lower the Q value until Q=K and equilibrium is established.

Q is larger than K in situations where there is more products than reactants, in which case the reverse reaction will be favored so that Q = K

I think it's helpful (at least for me) to remember what Dr. Lavelle said about not thinking of Q > K as "overshooting". One example would be perhaps after reaching equilibrium, some reactant is consistently being used up in another reaction, so even though the backward reaction proceeds, Q remains larger than K.

If the ratio of products to reactants is larger than that of the equilibrium constant, then Q>K

If one were to manually add products to a system at equilibrium, Q would be greater than K until the system rebalanced itself.

Q is greater than K when there more products than the equilibrium concentration of products.

If there is more products than reactants, Q will be greater than K, and the reverse reaction will be favored.

Q will be greater than K when the ratio of products to reactants is bigger.
