A. Increasing the temperature B. Increasing the concentration of reactants C. Removing the catalyst D. Increasing the pressure 相关知识点: 试题来源: 解析 C。解析:去除催化剂会减慢反应速率。增加温度、增加反应物浓度和增加压力通常会加快反应速率。反馈...
sat2普林斯顿化学题 reaction rate can be increased by increasing the surface area of reactants144页18题为什么选项A不对:Ca(aq) + CO3(aq) = CaCO3(S) (不会打右上角脚标因此省略)增大反应物面积一定要是固体和液体吗,溶液和溶液不行吗?
Optimum emulsion reassociation rates are obtained by vigorous shaking of the emulsion. At high DNA concentrations the rate depends on the violence of shaking. The fragment size of the DNA used in the emulsion reaction does not greatly influence the rate of reassociation. DNAs from viruses, ...

Gas-phase kinetic study of the silylene addition reaction to acetylene and acetylene-d2 over the temperature range 291–613 K Time-resolved studies of silylene, SiH2, generated by laser-flash photolysis of phenylsilane, have been employed to obtain rate constants for its bimolecul... R Becerra...
Activity of carbamoylphosphate synthetase I, the rate-limiting enzyme for Arg synthesis in the urea cycle, is allosterically activated by N-acetylglutamate (Grisolia and Cohen, 1953). The fact that we did not detect increases in urea, ornithine, or putrescine in response to LT1.3, LI1.29, ...
? 2021 Elsevier B.V.Aiming at improving the activity of supported catalysts toward oxidative desulfurization (ODS) reaction, an increasing support utilization rate strategy is developed by introducing additional phosphotungstic acid (HPW) on V anchored zeolite SiBeta. Both the Keggin HPW on the surfac...
