Consider the four statements below concerning limiting reactants in chemical systems. Identify the one that correctly describes the role of the limiting reactant.
- A. The limiting reactant is the one with the greatest coefficient in the balanced equation
- B. The limiting reactant determines the overall order of reaction in the rate law
- C. The limiting reactant is the one with the smallest coefficient in the balanced equation
- D. The limiting reagent is the reactant that is completely used up in a reaction,
Step-by-step solution
The limiting reactant is the reactant that is entirely consumed when a reaction goes to completion, thereby determining the maximum amount of product formed. Options A and C incorrectly focus on coefficients, while B confuses limiting reactant with reaction order. Hence, D is correct.
