Characteristics of First-Order Reactions

ln[A]0 – ln([A]0x) = kt
log([A]0x) = log[A]0Description: 34760.png
It may also be written as [A]t = [A]0 ekt.
The equation, which is known as Wilhelmy’s equation, indicates that the concentration of A decreases exponentially with time. The decrease is such that the time required for a definite fraction of the reaction to occur is independent of the initial concentration of the reactant.
