collision theory

Question 1

activation energy

Answer 1

the energy required for particles to collide and react with eachother

Question 2

factors that effect rate of reaction in particles

Answer 2

• amount of energy in particles
• frequency of collisions
• temperature
• concentration
• surface area

Question 3

how does the amount of energy in particles effect rate of reaction

Answer 3

more energy can be transferred during the collision

Question 4

how does frequency of collisions affect rate of reaction

Answer 4

the more they collide, the more successful collisions there will be

Question 5

how does concentration/pressure affect rate of reaction

Answer 5

there will be more particles per volume and therefore more collisions will occur

Question 6

how does surface area affect rate of reaction

Answer 6

there will be a higher area in which collisions with reactants take place, therefore leading to higher frequencies of collisions

Question 7

define FULLY what a catalyst is

Answer 7

speeds up the rate of reaction by lowering the activation energy and providing alternate pathways for the reaction
