# What is the rate determining step in a reaction coordinate diagram?

## What is the rate determining step in a reaction coordinate diagram?

Given a reaction coordinate (energy diagram), the rate determining step can be determined by taking the largest energy difference between any starting material or intermediate on the diagram and any transition state that comes after it. That transition state will then be the rate-determining step of a given reaction.

## How do you determine which step is the rate determining?

Rate determining step is the slowest step within a chemical reaction. The slowest step determines the rate of chemical reaction. The slowest step of a chemical reaction can be determined by setting up a reaction mechanisms. Many reactions do not occur in a single reaction but they happen in multiple elementary steps.

Which step is the rate determining step in a reaction and why?

Solution : Slowest step is the rate determining step.

### How many steps are in a reaction diagram?

The reaction involves two steps, step 1 is the slowest step and step 2 is the fastest step. Both steps are exothermic. Indicate on the diagram the overall enthalpy change of the reaction, the reaction for the transition states and intermediate states.

### Which step of a reaction is the rate determining step Brainly?

(b) The rate-determining step is the elementary reaction that controls the mathematical form of the overall rate law. The rate-determining step is usually the slowest elementary reaction. 6.

Why is the slow step the rate-determining step?

Rate-determining steps are slow because of how the mechanism works, which is just another way of saying “it is what it is”, and isn’t much of an answer.

#### Is the transition state the rate-determining step?

From the Wade textbook on kinetics and activation energy: the rate-determining step, is the step which leads to the transition state with the highest overall energy.

#### Is the first step always the rate determining step?

Many reaction mechanisms contain one step that is much slower than the others; this step is known as the rate-determining step. If the rate-determining step is the first step in a mechanism, the rate law for the overall reaction can be derived directly from the stoichiometry of the step’s balanced equation.

What is elementary step in a reaction?

An elementary reaction is a reaction that occurs in a single step. The rate law for an elementary reaction can be derived from the coefficients of the reactants in the balanced equation. For example, the rate law for the elementary reaction 2A + B → products is rate = k[A]²[B].

## What is rate-determining step class 12?

The slowest step during a chemical reaction determines the overall speed of a reaction towards completion is called rate determining step.

## What is meant by rate-limiting step?

Instead, the rate-limiting step is defined as the slowest step out of all the steps that occur for a given chemical reaction. In other words, a reaction can only proceed as fast as its slowest step, just like a chain is only as strong as its weakest link.

How many steps are in the reaction coordinate?

### How many steps are involved in the reaction in energy diagram?

The reaction whose potential energy diagram is shown in the figure is a two-step reaction. The activation energy for each step is labeled Ea1 and Ea2. Each elementary step has its own activated complex, labeled AC1 and AC2.

### Is the rate-determining step the highest peak?

Which is the rate-determining step of Michaelis Menten kinetics?

The breakdown of ES complex
Explanation: The breakdown of ES complex is the rate determining step of Michaelis Menten kinetics.
