Rate of reactions

Question 1

What is the rate of reaction?

Answer 1

• The speed at which the reactants are turned into products

Question 2

What two things can we measure to find the rate of reaction?

Answer 2

• The time taken for reactants to get used up
• The time taken for products to be formed

Question 3

What are the two equations for rate of reaction?

Answer 3

• ROR = Quantity of products formed / time taken
• ROR = Quantity of reactants used / time taken

Question 4

What is the reality of the rate of reaction through a whole reaction?

Answer 4

• At the beginning of the reaction, the rate will be very high as lots of reactants are available to react
• As the reaction progresses, the rate decreases as less reactants are available to react
