Collision Theory and Reaction Rates

Front

What is Collision Theory?

Back

Collision Theory states that for a reaction to occur, reactant particles must collide with sufficient energy and proper orientation.

Front

What factors affect the rate of reaction?

Back

Factors include temperature, concentration, surface area, and the presence of catalysts.

Front

How does surface area affect reaction rates?

Back

Increasing surface area allows more particles to collide, increasing the rate of reaction.

Front

What is activation energy?

Back

Activation energy is the minimum energy required for a chemical reaction to occur.

Front

How does temperature affect reaction rates?

Back

Increasing temperature increases the kinetic energy of particles, leading to more frequent and effective collisions.

Front

What happens to reactant concentration as a reaction proceeds?

Back

The concentration of reactants decreases as they are converted into products.

Front

What happens to product concentration as a reaction proceeds?

Back

The concentration of products increases as reactants are converted into products.

Front

What is a catalyst?

Back

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

Front

How does crushing a solid reactant affect the reaction rate?

Back

Crushing increases the surface area, allowing more collisions and thus increasing the reaction rate.

Front

What is the relationship between collision frequency and reaction rate?

Back

Higher collision frequency generally leads to a higher reaction rate.
