We’re being asked to determine the time it would take for the concentration of A to decrease from 0.860 M to 0.310 M.
The integrated rate law for a first-order reaction is as follows:
[A]t = concentration at time t
k = rate constant
t = time
[A]0 = initial concentration.
A first order reaction has a rate constant of 0.500 s–1. How long, in seconds, would it take for the concentration of A to decrease from 0.860 M to 0.310 M?
