Rates of Reaction

Question 1

what are the two equations to work out the mean rate of reaction

Answer 1

quantity of product formed divided by
time taken

2.
quantity of reactant used divided by
time taken

Question 2

describe the effect of concentration on the rate of reaction

Answer 2

the higher the concentration = the higher the number of frequent successful collisions = faster rate of reaction

Question 3

why do we have more product at the end of a reaction with a high concentration?

Answer 3

because we had more reactant molecules to begin with

Question 4

describe the effect of surface area on the rate of reaction

Answer 4

larger surface area = more successful collisions per second = faster rate of reaction

Question 5

describe the effect of temperature on the rate of reaction

Answer 5

increasing the temperature = particles have more energy = particles move faster = more successful collisions per second = faster rate of reaction
