The log fraction of THCA present decreases steadily over time, and the rate of decrease varies according to temperature. At 10-degree increments from 100 to 140 °C, half of the THCA is consumed in 30, 11, 6, 3, and 2 minutes; hence the rate constant follows <a href="/wiki/Arrhenius%27_law" class="mw-redirect" title="Arrhenius&#39; law">Arrhenius' law</a>, ranging between 10<sup>−8</sup> and 10<sup>−5</sup> in a linear log-log relationship with inverse temperature.
