Question

Explain rate of reaction using collision theory?

Answer 1

$\huge\red{Answer}$

In order for chemical reactions to occur, the reactant particles must collide with each other with sufficient energy (called en effective collision). This will lead to a chemical reaction in which existing chemical bonds are broken and new bonds are formed.

In the video, the same powdered material is burned in two different ways.

When in a pile, the powder has less surface area exposed to the air which means there are less effective collisions with oxygen.

When suspended in air, the powder has much greater surface area exposed to the air. This means there will be a much greater frequency of effective collisions with oxygen and a faster rate of reaction.

Collision theory, theory used to predict the rates of chemical reactions, particularly for gases. The collision theory is based on the assumption that for a reaction to occur it is necessary for the reacting species (atoms or molecules) to come together or collide with one another.....
