(a) Why the rate constant of a reaction decreases with increasing activation energy has to be explained. Concept introduction: Arrhenius equation: Arrhenius equation is a formula that represents the temperature
Several rational models are constructed to show why the ratio of a country's foreign trade to its GNP should decrease with increasing country size. A physics-inspired model of absorption of a quasi-continuous particle flow by a quasi-homogeneous space results in detailed agreement with the ...

" Yes, it's perfectly normal. If you've been monitoring your heart rate during exercise over an extended time, you know that it changes from one training session to another. The same route that felt easy yesterday might suddenly feel like someone set your world at a 2% incline....
This article quantifies the stages of drug discovery in which improvements in the time taken, success rate or affordability will have the most profound overall impact on bringing new drugs to market. Changes in clinical success rates will have the most profound impact on improving success in ...
2. Extra time to pay taxes you owe If you owe a balance due to the IRS, you may still have a good reason to file your tax return as soon as you can. If you submit your return in the middle of January, you do not have to pay taxes you owe until thefiling deadline.Preparing yo...

thermodynamics yields no information about the rate of the reaction. Because the tools and concepts of thermodynamics are very powerful, they were extended to allow an understanding of why reactions occur with different rates. If a maximum energy state exists intermediate between S and P, and...
The rate at which functional tumour vasculature is generated follows the Michaelis-Menten kinetics depending on the pro-angiogenic factor concentration, where a constant dispersal rate of endothelial cells (vasculature) is assumed. Notice that the Michaelis-Menten term is commonly used to model a ...
Vasoconstriction at the site of injury decreases the bleeding rate and allows platelets and activated coagulation factors to seal off the vascular breach by clot formation [9] (Fig. 2). Fibrinolysis regulates coagulation [10]. In the most favorable scenario, bleeding stops or decreases substantially...
