👉 The limiting fluid, also known as the minimum fluid required for a reaction to occur, is the fluid component that determines the maximum rate at which a chemical reaction can proceed under given conditions. It is the fluid part of the system that, when present in the smallest quantity, restricts the reaction's speed because it is the one that must be depleted first. In a reaction mixture, if the limiting fluid is scarce, the reaction will slow down or stop entirely until that fluid is completely consumed. This concept is crucial in optimizing reaction conditions in chemical processes, ensuring that the most critical reactant is adequately present to maximize yield and efficiency.
