In a concentration cell, why does the product concentration need to be lower than the reactants?

Because the addition of the electron into the products cause the ions to aggregate into solids, which will accumulate on the electrode that's in the solution- so you're making more of the inert substance.

Ions will form at the electrode where the ion concentration is lower in order to reach equilibrium. In a concentration cell, the reactants and products are the same ions except their concentrations; hence, the product ions form at the side with the lower ion concentration.
