A step that makes up a reaction is a specific molecular event that occurs during the chemical transformation of reactants into products. Each step involves the breaking and formation of chemical bonds between atoms to create new substances. These individual steps collectively make up the overall reaction mechanism.
What else can I help you with?
What do we call each step that makes up a reaction mechanism?
Each step in a reaction mechanism is referred to as an elementary step.
Is the transition state the slowest step in a reaction mechanism?
The transition state is not a step in a reaction mechanism; it is a high-energy state that exists at the peak of the reaction potential energy diagram. The slowest step in a reaction mechanism is often referred to as the rate-determining step, which has the highest activation energy and determines the overall rate of the reaction.
What is an elementary step and how is it related to the mechanism of the reaction?
An elementary step is a single step in a reaction mechanism that involves a single collision or event between molecules. The overall reaction mechanism is made up of a series of elementary steps that collectively describe how reactants are transformed into products. The rate of the overall reaction is determined by the slowest elementary step, known as the rate-determining step.
Which is the committed step of glycolysis?
The committed step of glycolysis is the reaction catalyzed by phophofructokine (PFK) converting fructose-6-phosphate into fructose-1,6- bisphosphate. The reaction is irreversible and secondly, it's the only reaction peculiar to the glycolysis.
What ways can a catalyst affect a chemical reation?
A catalyst affects a reaction by speeding it up. A catalyst, remember, does not participate as a reactant or product in the reaction. It facilitates the reaction by lowering its activation energy, making the reaction easier to happen.
What do we call each step that makes up a reaction mechanism?
Each step in a reaction mechanism is referred to as an elementary step.
Are products used up in a reaction?
No. Products are produced by a reaction. However, products may be used as reactants in a multi-step reaction.
What is the rate-limiting step of an enzyme-catalyzed reaction?
The rate-limiting step of an enzyme-catalyzed reaction is the slowest step in the reaction that determines the overall rate at which the reaction proceeds.
What does the rate determining step graph reveal about the reaction mechanism?
The rate determining step graph shows the slowest step in a reaction, which determines the overall rate of the reaction. This step often indicates the mechanism of the reaction, as it is typically the step with the highest activation energy.
What makes a catalyst very unusual?
It is not used up in the reaction.
What makes a reaction proceed faster without itself being used up during the reaction?
catalyst

The rate of the overall reaction is determined by the slowest elementary step, known as the rate-determining step.
What is the significance of the rate determining step in a reaction coordinate diagram?
The rate determining step in a reaction coordinate diagram is important because it determines the overall speed of the reaction. It is the slowest step in the reaction and sets the pace for the entire process. By understanding and optimizing the rate determining step, scientists can control and improve the efficiency of chemical reactions.
Does vinegar and baking soda create a big chemical reaction?
it makes a chemical reaction but not a big one. it just bubbles up and then stops.
How is the molecularity of the rate-controlling step related to the overall reaction order?
The molecularity of the rate-controlling step may not necessarily be the same as the overall reaction order. The rate-controlling step is determined by the slowest step in a reaction mechanism, while the overall reaction order is the sum of the individual reactant concentrations in the rate law equation. It is possible for the molecularity of the rate-controlling step to influence the overall reaction order, but they are not always directly correlated.
What is the function of chart wizard in Microsoft Excel?
It is normally near the right end of the Standard toolbar. When you rest the mouse pointer over it, it will say what it is. Another way is to go to the View Menu and Toolbars to see what toolbars are displayed, in case your Standard toolbar is off. There will be a tick beside it to show if it is on or not. You can also customise your toolbars from there.
