17 How does a catalyst increase the speed of a reaction? D A by increasing the collision frequency of particles B by increasing the speed of the particles C by increasing the temperature of the reaction D by lowering the activation energy 相关知识点: 试题来源: 解析 D 反馈 收藏 ...
Catalyst:A catalyst can never act as a reactant in a particular reaction in which it is increasing the rate of reaction. If a catalyst is present in reaction then the required energy gets decreased, whereas there is no change in kinetic energy....
10 How does the addition of a catalyst to a reaction affect the shape of the Maxwell-Boltzmann distribution curve? B A There is no change. B The peak moves to the left and is higher. C The peak moves to the right and is lower. D The total are a under the curve increases. ...
catalyst surface area (for a solid reactant) and, in some cases, light energy My question is: if I increase the temperature, will the rate of reaction still increase for a reaction involving reactants and products in gaseous states? I know that the rate constant of the reactio...
To determine the factor on which the rate constant does not depend, we can analyze the factors affecting the rate constant (K) in a chemical reaction. Here’s a step-by-step solution:Step 1: Understand the Rate Constant The rat
Explain the role of enzymes in a living cell. How do most cells regulate the activity of enzymes? What would happen to chemical reactions without enzymes? How do enzymes increase the rate of a chemical reaction? How is the rate of an enzyme catalyzed reaction affected by increasing enzyme con...
Catalysts participate in the reactions, but are neither reactants nor products of the reaction they catalyze. In the human body, enzymes are naturally occurring catalysts responsible for many essential biochemical reactions. In the catalytic converter, there are two different types of catalyst at ...
Owing to recent developments and implications inspired by fourth industrial revolution (4IR) technologies in the global manufacturing sector through the Industry 4.0 (I4.0) concept, this study was conducted to discover the impacts of I4.0 and environmental quality on the South African manufacturing sec...
