Sep 26, 2017 · Groups that can donate electron density to the ring make EAS reactions faster. If a substituent increases the rate of reaction relative to H it is called activating. If it decreases the rate relative to H it is called deactivating. (These rates need to be measured by experiment). Important!
Aug 11, 2022 · Figure 10.3.7 10.3. 7: The addition of a catalyst to a reaction lowers the activation energy, increasing the rate of the reaction. The activation energy of the uncatalyzed reaction is shown by Ea E a, while the catalyzed reaction is shown by E′a E a ′. The heat of reaction (ΔH) ( Δ H) is unchanged by the presence of the catalyst.

Jan 14, 2018 · Sensitivity and specificity of the RF test at cutoff points of 10 to 40 mIU/ml are shown in Table 1. The sensitivity was 92.1% at a cutoff level of 15 mIU/ml as recommended by the manufacturer, and decreased to 90.5% and 88.9% at 20 and 25 mIU/ml, respectively. The specificity was calculated sepa-rately using the blood donors, non-RA patients ...
