Explain how a catalyst aids chemical reaction to take place and identify the subsequent chemical changes in the reaction?
A catalyst provides an alternative pathway with lower activation energy for the reaction to proceed, allowing it to occur at a faster rate. This facilitates the formation of the products. In terms of chemical changes, the catalyst itself is not consumed or altered in the reaction, and the overall stoichiometry and composition of the reactants and products remain the same.
What cellular process would be directly affected by a biological catalyst that blocks a certain step in the separation of chromosomes?
The biological catalyst that blocks a step in the separation of chromosomes would directly affect the process of cell division, specifically the phase of mitosis called anaphase. This disruption would prevent the chromosomes from properly segregating and result in improper distribution of genetic material to the daughter cells.
What is a step rate modification?
A step rate modification is an adjustment made to the interest rate of a loan at set intervals, such as every few years or when certain conditions are met. It allows for changes to the interest rate based on specific criteria outlined in the loan agreement. This modification can result in either an increase or decrease in the interest rate for the borrower.
Which enzyme catalyzes the rate-limiting step of glycolysis?
Phosphofructokinase (PFK)
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 can you do to speed up the synthesis of iron oxide besides with water?
i dont think you can effect the rate determining step in that reaction. it is a very slow process. however temperature affects the rate of almost every reaction, aswell as concentration just water, perhaps a catalyst? not much else you can do for a solid.
What do you think the diagram would look like if a catalyst were added?
If a catalyst were added to a reaction diagram, it would typically be shown as a separate step or pathway with lower activation energy compared to the uncatalyzed reaction. The overall energy profile of the reaction would be shifted downward, indicating that the catalyst lowers the activation energy required for the reaction to proceed, leading to an increased reaction rate.
What the functions of sulfuric acid in iodine clock reaction?
In the iodine clock reaction, sulfuric acid is used as a catalyst to increase the reaction rate. It helps in the oxidation of iodide ions by hydrogen peroxide, which is a key step in the reaction. Sulfuric acid also provides the acidic environment necessary for the reaction to occur.
How to determine the rate determining step from a graph?
To determine the rate-determining step from a graph, look for the slowest step where the rate of reaction is the lowest. This step will have the highest activation energy and will be the one that controls the overall rate of the reaction.
Is rate limiting step and regulatory step same?
The rate-limiting step and the regulatory step are related concepts in metabolic pathways, but they are not the same. The rate-limiting step is the slowest reaction in a pathway, which determines the overall rate of the process. In contrast, a regulatory step refers to any step in a pathway that can be modulated by various factors, such as enzymes, allosteric regulators, or feedback mechanisms. While the rate-limiting step is often a regulatory step, not all regulatory steps are rate-limiting.
What is the rate law that is consistent with the proposed mechanism?
The rate law that is consistent with the proposed mechanism is determined by the slowest step in the reaction, known as the rate-determining step. This step will dictate the overall rate of the reaction and the rate law will be based on the reactants involved in this step.
How can one determine the rate-determining step from a graph?
To determine the rate-determining step from a graph, look for the slowest step where the rate of reaction is the lowest. This step will have the highest activation energy and will be the one that controls the overall rate of the 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.
How is the effect of concentration changes on the reaction rate seen in the rate law?
The exponents determine how much concentration changes affect the reaction rate
A cause and effect essay should be sequential meaning it?
presents the cause and effect relationship in step-by-step order.
