Collision Theory

Question 1

What does collision theory state

Answer 1

Chemical reactions can occur only when reacting particles collide with each other and with sufficient energy

Question 2

How does increasing temperature effect rate of reaction?

Answer 2

Increasing the temperature increases rate of reaction as particles have more energy and move faster, resulting in more frequent and energetic collisions

Question 3

How does increasing concentration / pressure effect rate of reaction?

Answer 3

Increasing the concentration / pressure increases rate of reaction as more particles are in the same space, making them more likely to bump into one another, resulting in more frequent collisions

Question 4

How does increasing surface area effect rate of reaction?

Answer 4

Increasing the surface area increases rate of reaction as more surfaces are exposed to the other reactants, resulting in more frequent collisions
