In most reactions, one reactant will be used up or consumed first. This reactant is known as the ____.
Answer
In most reactions, one reactant will be used up or consumed first. This reactant is known as the limiting reagent.
Note: Figure 4.7 shows a reaction vessel that has significant amounts of reactants A and B, which react in equal amounts to produce product C. On the left, before the reaction, there is more reactant A than B. After the reaction is over, there is more product C but there is reactant A left over. Thus, reactant A is considered in excess, and reactant B is considered limiting.
