A complete derivation, from first principles, of the reaction-rate formula for a generic process taking place in a heat bath of finite volume is given. It is shown that the formula involves no finite-volume correction. Through perturbative diagrammatic analysis of the resultant formula, the detail...

𝐻 is the relative humidity, 𝑘𝐷𝑃(𝑇,𝐻) is the reaction rate, and 𝜔∗𝐷𝑃=0.953±0.001 is the 𝐷𝑃 maximum fractional loss for linen [8]. Notice that 𝐶𝐵𝑛𝑜𝑟 is a nonlinear exponential function of 𝑇 and 𝐻, both of which are time varying, and ...
Abstract Absolute rate constants for the reaction OH+H2CO have been measured over the temperature range 228–362 K using the flash photolysis–resonance fluorescence technique. The results were independent of variations in [H2CO], total pressure [Ar] and flash intensity (i.e., initial [OH])....
This will lower your body core temperature, decrease the heart rate's response to exercise, and reduce the chances of dehydration. 这样做会降低你的体温和运动时的心率,并减少脱水的几率。 xiaozu.renren.com 2. Analysis result shows that the great temperature decrease in reaction oil and gas pipe...
