The rate constant for a reaction is nearly doubled with about 10∘ rise in temperature. The reason is that the number of effective collision becomes almost double. The exact dependence of the rate of reaction can be given by Arrhenius equation, k=Ae−Ka/RT. Where, A is called the fre...

Effect of temperature, solvent polarity, and nature of lewis acid on the rate constants in the carbocationic poly- merization of isobutylene. Macromolecules. 2003;36:8282-8290.Laszlo Sipos,Priyadarsi De,Rudolf Faust.Effect of Temperature, Solvent Polarity, and Nature of Lewis Acid on the Rate ...
The effect of temperature on the dynamic parameters of silty clay in a seasonally frozen region was assessed using a GDS dynamic triaxial test system. The strength parameters, dynamic elastic modulus, damping ratio, and other dynamic parameters of the soil samples were analyzed under different temper...
Temperature is known to have a significant impact on the performance, safety and cycle lifetime of lithium-ion batteries (LiB). However, the comprehensive effects of temperature on the cyclic aging rate of LiB have yet to be found. We use an electrochemistry-based model (ECBE) here to measu...
These results suggested that k1 as well as k2 depended on temperature, and were larger at higher temperature. The present study indicated that both water temperatures of 20 and 25°C were suitable for the bioconcentration experiment using these fish species, and that the water temperature in the...
31℃ and 35℃.The highest survival rate of larvae from the larval stage of Z1 to P15 was 29.8% at 31℃,followed by 33℃(20.9%),29℃(14.6%) and 35℃(4.7%).During the experiment,larvae grown at 31℃ kept the best state and were the most stable.Therefore,the optimum temperature for...
Environmental variables such as temperature are important factors that affect the efficiency of biological control agents. This study examined the effect of temperature on the sex ratio, longevity, oviposition periods, fecundity and life table parameters of the predatory thrips Scolothrips longicornis Prie...
The rate of a chemical reaction is affected by temperature. Explore this process, learn about the Arrhenius equation, review the exponential...
