WebChapter 12: Chemical Kinetics. ... The units for a rate constant will vary as appropriate to accommodate the overall order of the reaction – remembering that rate is always reported as $\frac{\Delta\:concentration}{\Delta\:time}$, and the units of concentration and time must be consistent across all terms in the rate law. ... WebApr 3, 2015 · The reactions were carried out at temperatures of 20, 30, 40, and 50°C. The experimental data was fitted to the nth-order kinetic models. The results indicate that the nth-order model gives a reasonable description of the hydrogen generation rate over all of the temperature range.
