concentration

Definition

Concentration in the context of chemical reactions refers to the amount of a substance (solute) present in a certain volume of solution. It significantly influences the rate and direction of chemical reactions in the body.

Analogy

Think of concentration like a crowded concert venue. The more people (or molecules of a substance) there are packed into a space, the higher the chances of interactions occurring, similar to how molecules react with each other more frequently in a highly concentrated solution.
