How long (in seconds) would it take for the concentration of A to decrease from 0.900 M to 0.330 M?

For this question, which equation should I use?

[Anthony_3C]

use the integrated rate law for zero order: [A] = [A0] -kt

[Armen_Isayan_2L]

Hello, for this question you would utilize the equation [A]t = -kt + [A]0, which you would then need to rearrange t, to determine the amount of time. The rearranged equation would be t = [A]0-[A]t / k, and all you would have to do is input the proper values to determine the number of seconds it would take for the concentration of A to decrease from 0.900M to 0.330M.
