Q. Write the difference between the order and molecularity of a reaction.
Answer:– The molecularity of a reaction refers to the number of molecules, atoms, and ions that must interact for the chemical reaction to take place in a certain amount of time. The fundamental distinctions between molecularity and reaction order are listed below.
Molecularity of reaction | Order of reaction. |
The molecularity of a rate-determining step refers to the number of ions or molecules involved. | The order of the reaction is the total of power to which the component concentrations are increased in the rate equation. |
By examining the reaction mechanism, the molecularity of an activity can be established. | The experimental procedures decide the order of the reactions. |
The rate-determining step determines the reaction’s molecularity. | The total of the degrees to which the component quantities are increased in the kinetic rate equation gives the reaction order. |
A reaction’s molecularity is a whole number apart from zero. | It can be a fraction or a whole number. As a result, it could be zero, one, two, three, or even a fraction of a number. |
