Final answer:
The rate of elimination being 10% per hour typifies a first-order reaction, where the reaction rate is proportional to the reactant concentration and the half-life does not depend on initial concentration.
Step-by-step explanation:
The rate of elimination of a substance being 10% (of concentration) per hour is an example of a first-order reaction. In a first-order reaction, the rate at which the reaction proceeds is directly proportional to the concentration of one of the reactants. In such reactions, a constant percentage of the reactant is consumed per unit time, and the half-life is independent of the initial concentration.
For example, a first-order chemical reaction is 97% complete after 5 half-lives and is considered 100% complete after 10 half-lives. This contrasts with a zeroth-order reaction, where the rate is constant and independent of the concentration of the reactants, and the half-life increases as the initial concentration increases.
