The rate of product formation or rate of loss of a reactant, in a chemical reaction has the unit of concentration per time. The concentration is typically an amount concentration, particle number density, or mass concentration (or several other related possibilities such as partial pressure, see ...

Results Post hoc analysis from the previous cohort yielded PRU of at least 220 as the optimal threshold for modified preparation selection. The thromboembolic event rate of the clopidogrel responders (one of 126 [0.8%]) was lower than that of the historical control group that received standard ...

Catalysis is the phenomenon in which a relatively small amount of a foreign material, called a "catalyst," augments the rate of a chemical reaction without itself being consumed. The catalyst enters into reaction but is regenerated at the end of each reaction cycle. Thus, one unit of catalyst...
摘要: Recent advances in FCC short contact time operations coupled with heavier feedstocks have resulted in more catalytic crackers operating in a mass transfer limited regime. The rate of mass transfer-not catalytic activity-determines the reaction rate in these units....
With dark green plants and algae our determinations of units by means of 40 microsec flashes superimposed on a steady rate of background photosynthesis at 900 ergs cm(-2) sec(-1) of red light yielded mostly numbers between 2000 and 2700. However, the photosynthetic unit turned out to be ...
