Collision theory

Question 1

What are the principles of collision theory?

Answer 1

• in order for partickes to react they must collide
• when particles react, chemical bonds must be broken which requires energy
• particles must collide in the correct orientation
• in order for a reaction to happen particles must collide with enough energy to start breaking the chemical bonds, if particles dont have eough energy, they will just bounce off eachother

Question 2

What is the rate of a reaction proportional to?

Answer 2

The rate of reactionis proportional to the number of effective collisions per second

Question 3

Ways to increase rate of reaction in a solution

Answer 3

• increase conc of reactants
  At a higher conc we have more reactant particles in the same volume because reactant particles are closer together , there is an increased chance of collisions taking place = increased frequency of collisions

Question 4

Ways to increase rofr in a gas

Answer 4

Increasing the presssure makes the partickes closer together which increases frequency of collisions = increased rate of reaction
