Question 1

finding the rate of reaction

Answer 1

• can find the rate of a chemical reaction by monitoring the amount of reactants used up over time
• can find out the rate of reaction by measuring the amount of products made over time

Question 2

mean rate of reaction

Answer 2

mean rate of reaction = quantity of reactant used / time

Question 3

collision theory

Answer 3

particles must collide with a certain minimum amount of energy, before they can react

Question 4

activation energy

Answer 4

minimum amount of energy that particles must have in order to react is activation energy of a reaction
