Finding order given half-life

[EmilyC_3D]

I remember from some of the questions, we were given the half-life for something and then told to find the order. To solve these problems, should we just guess and check using the half-life equations or is there another trick to it?

[Nathan Chu 3H]

Yes, I believe I just did guess and check using the half-life equations. I'm not sure if there is a more efficient method.

[Katie Lam 2J]

Yes, I believe we just have to see which half-life equation matches the given half-life and rate constant.

If you are given the half life you can use the three half life equation to match the half rate and therefore, it will also allow you to find the order.
