Reaction Rates and Collision Theory

Theory used to predict the rates of chemical reactions, particularly gor gasses.

• The colision theory

• The collition theory

• The collision theory

- Is a substance which when added to a reaction mixture, increases the rate of a chemical reactions but is not changed pr used after the reaction in finished.

• Catalyst

• Coefficient

• Concentration

• Particle size

• Temperature

The rate of chemical reaction increases with increasing temperature

• Temperature

• Reaction rate

• Concentration

• Catalyst

• Particle size

When on the reactant is solid, the reaction happens on the surface of the solid. If the solid is broken up to smaller pieces more surface area is exposed and there are more places where collision can occur.

• Particle size

• Concentration

• Temperature

• Catalyst

• Coefficient

What is collision theory?

• Molecules must collide in the correct orientation with enough energy to bond.

• Molecules need enough energy to collide and react.

• Atoms constantly collide and react.

• The minimum energy needed for atoms to react

Increasing the temperature of your solution will.......

• Not affect the rate of reaction.

• Speed up the rate of reaction

• Slow down the rate of reaction

If the reactant particles collide with less than the activation energy, the particles will be rebound, and no reaction will occur.

• True

• False

The collisions which bring about a chemical reaction are called: 

• Consistent collisions

•  Normal collisions 

• Effective collisions 

• None of the above

More collisions correspond to a: 

• Faster reaction rate  

• Slower reaction rate

• Constant reaction rate 

• None of the above
