What is Collision Theory?

Back

Collision Theory explains how chemical reactions occur and why reaction rates differ for different reactions. It states that for a reaction to occur, reactant particles must collide with sufficient energy and proper orientation.

What factors affect the rate of a chemical reaction?

Back

The rate of a chemical reaction can be affected by factors such as temperature, concentration of reactants, surface area, and the presence of a catalyst.

Front

How does surface area affect reaction rates?

Back

Increasing the surface area of a reactant increases the number of collisions between reactant particles, leading to a higher reaction rate.

Front

What is a catalyst?

Back

A catalyst is a substance that increases the rate of a chemical reaction without being consumed in the process.

Front

How does temperature influence reaction rates?

Back

Increasing temperature increases the kinetic energy of particles, leading to more frequent and energetic collisions, which increases the reaction rate.

Front

What is the effect of concentration on reaction rates?

Back

Higher concentration of reactants leads to more collisions per unit time, thus increasing the reaction rate.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the average kinetic energy of particles increases, resulting in more energetic collisions.

Front

What happens to a catalyst at the end of a reaction?

Back

A catalyst remains unchanged at the end of a reaction and can be used repeatedly.

Front

What is the role of orientation in collisions?

Back

For a reaction to occur, reactant particles must collide in the correct orientation to break bonds and form new ones.

What is the significance of activation energy?

Back

Activation energy is the minimum energy required for a reaction to occur. It represents the energy barrier that must be overcome for reactants to transform into products.
