The half- life of a first- order reaction .

Question

Quizplus · Accepted Answer

- The half-life of a first-order reaction is constant, as it is determined solely by the rate constant of the reaction.
- The half-life of a first-order reaction does not depend on the initial reactant concentration, as it is a characteristic of the reaction itself.
- The half-life of a first-order reaction can be calculated from the reaction rate constant using the equation t1/2 = ln(2)/k.
- The definition of half-life is the time necessary for the reactant concentration to drop to half its original value. Therefore, this statement is also correct.
