How do you determine if a reaction is an elementary step?

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 qualifies an elementary reaction?

An elementary reaction is a chemical reaction in which one or more chemical species react directly to form products in a single reaction step and with a single transition state. An example of this type of reaction is a cycloaddition reaction.

Which of the following is true about elementary reaction?

Which of the following is true about elementary reactions? Explanation: The order of an elementary reaction can never take fractional values. Elementary reactions occur in a single step.

Is elementary reaction first order?

The overall rate of a reaction is determined by the rate of the slowest step, called the rate-determining step. Unimolecular elementary reactions have first-order rate laws, while bimolecular elementary reactions have second-order rate laws.

Which among the following is elementary reaction?

Which among the following reactions is elementary? Explanation: Ester formation is an elementary reaction.

Which of the following is correct about order and molecularity for an elementary reaction?

The correct statement are: 1. for an elementary reaction order and molecularity are same 2. Reactions having order and molecularity lt3 are rate 3. Rate of reaction is decided by slowest step of mechanism 4.

How do you determine which elementary step is the slowest?

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.

How do you determine if a reaction is first order or second order?

Initial Rate (M/s) Determine the reaction order and the rate constant. If a plot of reactant concentration versus time is not linear but a plot of 1/reaction concentration versus time is linear, then the reaction is second order.

How do you determine order of reaction with respect to each reactant?

The overall reaction order is the sum of the orders with respect to each reactant. If m = 1 and n = 1, the overall order of the reaction is second order (m + n = 1 + 1 = 2).

Which of the following is true A if we know that a reaction is an elementary reaction?

Possible Answers: If we know that a reaction is an elementary reaction, then we know its rate law. Since intermediate compounds can be formed, the chemical equations for the elementary reaction in a multistep mechanism do not always have to add to give the chemical equation of the overall process.
