Collision Theory

Question 1

According to the collision theory, what are the prerequisites for an effective collision to occur?

Answer 1

• reactants both have sufficient energy to overcome the activation energy requirement
• collision has proper orientation (head-to-head)

Question 2

Factors affecting speed of reaction:

Answer 2

• concentration
• pressure
• temperature
• surface area
• presence of catalyst

Question 3

Define catalyst

Answer 3

A substance that can alter the speed of a reaction without taking part in it

Question 4

Basics of the collision theory:

Answer 4

• a chemical reaction occurs when 2 particles collide

- not all collisions are effective
