rates of reaction - catalysts

Question 1

what do catalysts do?

Answer 1

spread up rate of reaction but are not used up during the reaction so it is reusable

Question 2

what is the importance of a catalyst?

Answer 2

allows us to carry out reactions quickly without needing to increase temperature. this saves money

Question 3

how do catalysts increase rate of reaction?

Answer 3

they provide a different pathway for reaction that has lower activation energy

Question 4

If a catalyst is present, what does this do for the particles?

Answer 4

they require less energy to overcome the activation barrier so more particles will have successful collins per second meaning rate of reaction will increase

Question 5

what don’t you include catalyst in?

Answer 5

chemical reaction formula as they aren’t used up like a reactant

Question 6

Different reactions need…..

Answer 6

different catalysts

Question 7

what do enzymes do?

Answer 7

act as catalysts in living organisms

Question 8

what do enzymes do?

Answer 8

act as catalysts in living organisms
