Question

Which statement about limiting and excess reagents is accurate?
options:
a) The excess reagent is the reactant that runs out in a chemical reaction.
b) The amount of product in a chemical reaction is determined by the amount of excess reagent.
c) The excess reagent is totally consumed by the end of the reaction.
d) None of the above.

Answer 1

Answer:

(a) The excess reagent is the reactant that runs out in a chemical reaction.

Explanation:

(b) is wrong. The amount of product is determined by amount of limiting reagent.

(c) is wrong. The limiting reagent is totally consumed by the end of the reaction.

Hence, it is excess reagent that remains in the solution.
