Rates of Reaction

Question 1

What does an ‘Enzyme’ do?

Answer 1

• Speeds up the reaction of digestion by breaking down the glucose molecules faster

Question 2

What are ‘Catalysts’?

Answer 2

• Chemicals that speed up chemical reactions but are not used in the process

Question 3

How do catalysts reduce levels of pollutants?

Answer 3

• By speeding up the reaction with oxygen

Question 4

Why do catalysts have a honeycomb structure?

Answer 4

• As it gives a bigger surface area, so more of the catalyst can collide with pollutant particles so they collide more frequently

Question 5

The speed of reaction happens at is called what?

Answer 5

• The rate of reaction

Question 6

What is the rate of reaction linked to?

Answer 6

• The number of collisons between particles

Question 7

What does the rate of reaction depend on?

Answer 7

• The frequency of successful collisons between particles
