rates of reaction

Question 1

what factors can affect the rate of reaction

Answer 1

temperature
particle size
concentration
catalyst

Question 2

describe the relationship between concentration and the rate of reaction

Answer 2

higher concentration = faster reaction rate

the higher the concentration, the more particles there are to collide, the faster the reaction rate

Question 3

describe the relationship between the temperature and the rate of reaction

Answer 3

higher temp = faster raection

the higher the temp, the faster particles will move so the more likley they are to collide

Question 4

describe the relationship of particle size on the rate of reaction

Answer 4

the smaller the particle size = faster the reaction rate

smaller the particle size means more surface area for prticles to collide, faster reaction rate

Question 5

describe the relationship between catalysts ans the rate of reaction

Answer 5

catalysts speed up the rate of reaction (remain unchanged and can be recovered)

Question 6

how do you calculate the avergae rate of reaction

Answer 6

average rate = change in quantity
———————————
change in time
