The phrase "a decrease in reaction" is correct and usable in written English.
It can be used in contexts discussing changes in responses, behaviors, or chemical reactions, among other scenarios.
Example: "The study showed a significant decrease in reaction times after the participants were given the new medication."
Alternatives: "a reduction in response" or "a decline in reaction".
This behavior was attributed to a decrease in reaction sites due to the formation of intermetallic compounds.
A decrease in reaction rate was observed with ASR as the surfactant in the MMA system but not in the SM system.
If we define the central flame zone as the region with temperature higher than 1300 K, one can observe that as the feed flow rate is increased from 0.0008 to 0.006 kg/s the flame central zone is smaller indicating a decrease in reaction temperature.
All participants improved their perceptual performance as reflected by an increase in sensitivity (d') and a decrease in reaction time.
Furthermore, this positive influence on accuracy was paralleled by a decrease in reaction times, but only among controls and not among CP participants.
Behaviorally, repetition suppression has been linked to repetition priming or a decrease in reaction time to respond to repeated or familiar stimuli [33], [34].
We designed a temperature programmed reduction analysis using ammonia gas to measure the amount of lattice oxygen release and identify a decrease in reaction-onset temperature from 136 °C to 75 °C upon doping the catalyst with Zr.
It is evident from data listed in Table 8 that, the values of (E_{text{a}}^{0}) are larger than corresponding values of (eta H_{text{a}}^{0}) indicating the corrosion process involved a gaseous reaction, simply the hydrogen evolution reaction, associated with a decrease in total reaction volume [39, 40].
Kinetic isotope effect for the N2 formation in NO CH4 O2 vs. NO CD4 O2 reactions was 1.65 at 673 K and decreased with a decrease in the reaction temperature.
UV vis illumination led to an increase in the reaction rate, related to the increment in the rate constant, and a decrease in the reaction orders for both CN− and OH− ions.
A decrease in the reaction rates was observed in temperature above 55 °C.
