rates of reaction CP2

Question 1

what is a catalyst

Answer 1

something that speeds up a reaction without loosing any energy

Question 2

what is activation energy

Answer 2

a reaction that only occurs if the particles collide with enough energy to break bonds
the am mount of energy needed

Question 3

what is an enzyme

Answer 3

a biological enzyme

Question 4

Use collision theory to explain why high concentration speeds up the rate of reaction

Answer 4

the particles will be closer together so there is more of a chance of the particles colliding

Question 5

Use collision theory to explain why higher temperature speeds up the rate of reaction

Answer 5

the particles move faster so they will collide more often

Question 6

Use collision theory to explain why higher pressure speeds up the rate of reaction

Answer 6

the higher the pressure the closer the particles will be together, they will also have more energy

Question 7

Use collision theory to explain why a catalyst speeds up the rate of reaction

Answer 7

the particles with have more energy to exchange meaning they will be more prone to collide
