temp and rate

Question 1

what 2 factors will temperature increase the rate of reaction through?

Answer 1

particles gain kinetic energy, move faster and collide more frequently (this effect is minor, there is only a slight change on collision frequency)

proportion of particles with activation energy (Ea) is increased

Question 2

does the energy change depend on the rate of reaction?

Answer 2

no

Question 3

what is activation energy?

Answer 3

the minimum energy required for particles to react (there may be more)

energy needed to break bonds in reactants

Question 4

what is the maxwell boltzmann distribution?

Answer 4

a graph with the energy on the x axis and the number of particles on the y axis

to show the relationship between the two factors for a reaction at different temperatures

Question 5

why are most collisions unsuccessful?

Answer 5

because one or both of the particles have insufficient energy

Question 6

why is it more likely that each collision will be successful at higher temps?

Answer 6

because at higher temps, a greater proportion of particles have the required activation energy

it is more likely that each collision will be successful

the frequency of successful collisions increases, so the rate increases
