\begin{equation}  A^i \to \mathrm{products}\quad\quad\textrm{for}\quad i=1,2,3,\ldots,n  \end{equation}  with themass-action  rate laws \begin{equation}  \frac{dC_{A^i}(t)}{dt} = k_iC_{A^i}(t). k_i(t)C_{A^i}(t).  \end{equation}  Experimentalists deduce rate laws from data that is the integrated rate law. For the $i^{th}$-order reaction the integrated rate law is  \begin{equation}
