Effect on concentration on rate

Question 1

What is collision theory?

Answer 1

• Chemical reactions can only take place when the reacting particles collide with eachother, The collisions must have sufficient energy.
• Rate of Reaction is determined by the frequency of sucessfull collisions.

Question 2

What happens to the rate of reaction when concentration increases?

Answer 2

• The rate of reaction is porportionate to the concentration.
• Applies to gas.
• More reactant molecules to react with.
