Which of the following most accurately defines the term “excess reagent”?
a. the reactant that is completely consumed in a chemical reaction
b. the reactant that determines how much product will be formed in a chemical reaction
c. a reactant that is still present after a chemical reaction is complete
d. none of the above
Answer:
The excess reactant is the reactant in a chemical reaction with a greater amount than necessary to react completely with the limiting reactant. It is the reactant(s) that remain after a chemical reaction has reached equilibrium.
