What is the name of the substance that changes the rate of a chemical reaction without being consumed? A. Reactant B. Product C. Catalyst D. Solute 相关知识点: 试题来源: 解析 C。这里考查“catalyst”(催化剂)的概念,它能改变反应速率但自身不被消耗。选项 A“reactant”是反应物;选项 B“...
In a chemical reaction, what will slow down the reaction rate? A. Increase surface area B. Higher temperature C. Decrease the amount of reactants D. Add an inhibitor 相关知识点: 试题来源: 解析 D。增加反应物的表面积和升高温度会加快反应速率。减少反应物的量不一定会明显减慢反应速率。添加...
This article presents information on ionic activity effects in reaction kinetics. Kinetics involve rate-determining steps, whereas equilibrium expressions concern the overall process. Still, in view of the usual kinetic explanation of the mass action law, one might expect the chemical rate expressions ...

Chemical reaction kinetics provide a quantitative or qualitative measurement of the rate(s) of reactions and provide insight into the dependence of these rates on variables such as concentration, temperature, pressure, the presence of catalysts, the physical state of the reactants, etc. Since chemi...
Learn the effect that temperature has on the process of diffusion to understand how to speed up the process and how to increase the rate of most chemical reactions. Diffusion is a process by which a concentrated group of molecules gradually becomes less concentrated, either by mixing with nearby...
The rate of a reaction actually measures the rate at which a reaction proceeds. i.e., it tells you the amount of reactants left or that reacted as a function of time. The rate constant is something that you need to incorporate in the rate equation in order to find out reaction rate...
What can affect the function of enzymes? Why do enzymes change with ambient temperature? How does temperature affect the action of enzymes on their substrates? How does enzymes effects the temperature on the rate of reaction? How does temperature affect enzyme activity? ...
What are the effects of concentration, pressure, particle size and temperature on the speeds of reactions?Factors Affecting Rate of a Reaction:Chemical kinetics deals with the rates of chemical reactions and the factors affecting them. The rate can be average or...
