Q10 ADJUSTMENT… This calculates the effect of temperature (Q10) on the rate of reactions or functions -- speed, power, metabolism, etc. To do that, enter a base temperature and an adjusted temperature, the base value of the rate function, and the Q10 (the default is 2.2), and click the 'compute adjusted value' button. Alternately, enter the base and adjusted temperatures and the base and adjusted rate values, and compute Q10 by clicking the 'compute Q10' button. Q10 is the factorial change in rate across a 10 °C temperature change. The temperature difference (base temperature to adjusted temperature) can be positive or negative.
