Unit of k

[Yifan_Wang_2A]

If the rate constant k is given in the unit of min^-1, do I have to convert it to seconds first or can I just use it in the integral rate law to find the concentration of the reactant and make every unit in minutes?

As long as you keep units that will be cancelled out consistent through all your steps, you should be fine. Personally though, I find it safer to convert everything into the standards (grams, seconds, rather than mg, minutes, etc.) Up to you, just make sure all units are consistent.

If you make the other units in minutes as well, that works. Hours or days also works as long as you keep the units consistent throughout.

IF you keep the other units matching then it is fine. You don't have to convert it to seconds if not asked to.
