Shelf life equation
WebMar 24, 2024 · The accelerated testing is only to save time. e.g. We believe 2 years is a reasonable shelf life based on what we know. But we don't want to wait for two years for test results. So we raise T and extrapolate results to room temperature. That, I believe, is the motivation behind accelerated testing. $\endgroup$ – WebFeb 12, 2024 · The differential equation describing first-order kinetics is given below: Rate = − d[A] dt = k[A]1 = k[A] The "rate" is the reaction rate (in units of molar/time) and k is the reaction rate coefficient (in units of 1/time). However, the units of k vary for non-first-order reactions. These differential equations are separable, which simplifies ...
