###### FREE Expert Solution

We're being asked to determine the order for which half-life period is independent of initial concentration.

Let's determine the equation for the half-life for each order of reaction:

A. Zero

Recall the equation for a zeroth-order half-life:

$\overline{){{\mathbf{t}}}_{\mathbf{1}}{\mathbf{2}}}{\mathbf{=}}\frac{{\left[A\right]}_{\mathbf{0}}}{\mathbf{2}\mathbf{k}}}$

B. First
