Collision Theory And Catalysts

Question 1

How do solid catalysts work?

Answer 1

They give the reacting particles a surface to stick to which increases the number of successful collisions

Question 2

How do catalysts reduce costs in industrial reactions?

Answer 2

• speeding up the rate of reaction saves money as more product can be produced in a shorter amount of time
• catalysts can reduce the amount of energy needed for the reaction to take place

Question 3

What are the disadvantages of using catalysts in industry?

Answer 3

• catalysts can be very expensive and can be difficult to be removed from the product
• different reactions use different catalysts
• catalysts can be poisoned by impurities making them useless

Question 4

What is a catalyst?

Answer 4

A substance which speeds up a reaction without being changed or used up in the reaction
