When the concentration of reactants in a chemical reaction is increased, what happens to the reactio

Increasing reactant concentration means more particles are present in the same space. More particles lead to more frequent collisions between molecules, causing reactions to occur faster.

Think of it like a crowded room versus an empty room. In a crowded room, people bump into each other more often than in an empty room.

Chemical reactions happen when particles collide with enough energy. Higher concentration creates more collisions per second, directly increasing the reaction rate.
