Using Half Life with Zero Order

$\frac{d[R]}{dt}=-k; [R]=-kt + [R]_{0}; t_{\frac{1}{2}}=\frac{[R]_{0}}{2k}$

Using Half Life with Zero Order

In the text book under the half life formula for zero order reactions it says not used. What does that refer to?

On page 631, the textbook also says that the half-life is not used for second order reactions. Maybe this is because the half-life depends on the initial concentration for zero and second order reactions? This would make it difficult to compare reactions.

I’m guessing that half life of a zero order reaction would be itself?
