Direct Tabular Method for Obtaining the Order of a Reaction of a Restricted Class

When the rate law of a process can be written in the form X$^{\prime}$ = dx/dt = -kX$^{m}$, the order m = XX$^{\prime \prime}$/(X$^{\prime}$)$^{2}$ may be calculated directly, in lieu of the usual trial-and-error methods. An analytical method is used to calculate the derivatives X$^{\prime}$ and X$^{\prime \prime}$ from the collected data, X, and t.
