Can a reaction be 5th order?

Re: Reaction Orders The order of reaction is the power of the reactant’s concentration term in the rate equation. Therefore, for a first-order reaction, rate=k[A]^1=k[A]; while for a second-order reaction, rate=k[A]^2; so on and so forth for third-order, fourth-order or fifth-order reaction.

Can an order of reaction be 4?

For example, for three first-order reactions of three reactants, the overall order of reaction is three. For two second-order reactions of two reactants, the overall order of the reaction is four.

What is the unit of rate constant for fifth order reaction?

Mol1−nlitren−1sec−1.

Why are 4th order reactions not possible?

so 4th order means 4th component, so 4 component coming together and reacting is a steric blunder and it can not react properly, so it is a impossible type.

Can order of reaction be determined experimentally?

The reaction order must always be determined experimentally.

What are the four factors that affect reaction rates?

The factors that affect reaction rates are:

• surface area of a solid reactant.
• concentration or pressure of a reactant.
• temperature.
• nature of the reactants.
• presence/absence of a catalyst.

What are the units for a fourth order reaction?

Therefore, the unit of k is (mol/L)−3t−1 for fourth order reaction.

What are the units of K in a fourth order reaction?

What are the units of order of reaction if its order is n?

For nth order reaction, the units of rate constant = (molL−1)1−n. s−1.

Why is the order of reaction not greater than 3?

(i) Proper orientation and effective collision of the reactants. (ii) the chances of simultaneous collision with proper orientation between more than 3 species are very rare, so reaction with order greater than 3 are rare. i.e., the rate of reaction will become 8 times the rate as in (1).

What are the 4 points of collision theory?

The collision energy must be greater than the activation energy for the reaction. The collision must occur in the proper orientation. The collision frequency must be greater than the frequency factor for the reaction. A collision between the reactants must occur.
