Question

The number of reacting molecules which collide
Simultaneously to bring
Chemical reaction is
known as​

Answer 1

Answer:

In this reaction, the molecularity is two. Therefore, molecularity is the number of reacting species (molecules, atoms or ions) that collide simultaneously to bring about a chemical reaction is called molecularity of a reaction

Answer 2

The number of reacting molecules that collide simultaneously to bring a chemical reaction is known as the molecularity of a reaction.

• Molecularity is simply the number of reacting species that form a product in the chemical reaction.
• For a complex reaction that involves multiple steps before the final product is formed, the molecularity is determined from the rate-determining step in the reaction.
• The chemical reactions can be categorized as unimolecular, bimolecular or trimolecular based on the number of reactants responsible for chemical reaction and product formation.
• For example, 2 HI → H2 + I2
• The molecularity of the reaction is two because 2 molecules of Hydrogen Iodide reacts to form products.
• Hence, the number of reacting molecules determine the molecularity of the reaction.
