When cocaine is eliminated from a human body, reaction concentration drops much faster at the outset than at later times. Of what type of reaction is this indicative?
A) A zero-order reaction
B) A first-order reaction
C) An elimination reaction
D) This makes no indication of reaction type.
Zero-Order Reaction
a chemical reaction in which the rate is independent of the concentration of the reactant(s).
Cocaine
A powerful stimulant drug derived from the leaves of the coca plant, used medically as a local anesthetic and often abused for its euphoric effects.
- Understand how the concentration of reactants affects the speed and order of reactions.
- Apply knowledge of reaction rates to pharmaceutical kinetics.

Final Answer :
B
Explanation :
This behavior is indicative of a first-order reaction, where the rate of reaction is directly proportional to the concentration of the reactant. In the context of cocaine elimination, this means that when there's more cocaine in the body, it's eliminated faster, and as the concentration decreases, the rate of elimination slows down.
