Will the half life equations be given to us or will we have to derive them?

While the formula sheets vary from year to year, it's likely that if these half-life equations were on the most recent exam, they will be on the final exam formula sheet. :)

On the equation sheet on the website, the half-life formulas are given. However, the equation sheet does not specify which order reaction each equation is for, so make sure that you know the difference between the equations.

Half life equations are given in the equation sheet, but they will not tell you which half-life equation corresponds to which order of reaction. You can also derive them using the standard half life equation, solving for t when the concentrations are half of the initial.

The half lives are provided on the formula sheet.

They will likely be on the formula sheet, but if you do need to derive the formula, plug in t=1/2 to get the half life formula.
