What is the unit of the rate constant of a first-order reaction?
Understand the Problem
The question is asking for the unit of the rate constant specifically for a first-order chemical reaction. To understand it, we recognize that the rate constant for a first-order reaction has a unit that reflects the concentration change per unit time, typically expressed in terms of molarity per second (M/s) or inverse seconds (s⁻¹).
Answer
s⁻¹
The unit of the rate constant for a first-order reaction is reciprocal seconds (s⁻¹).
Answer for screen readers
The unit of the rate constant for a first-order reaction is reciprocal seconds (s⁻¹).
More Information
The rate constant's unit for first-order reactions reflects the dependence on the time variable, as concentration changes linearly with time.
