3.1.5.3 Effect of Temperature on Reaction Rate

Question 1

How does temperature affect reaction rate?

Answer 1

More kinetic energy = particles are faster = particles collide more = more particles have enough energy to collide = increased proportion of successful collisions = higher rate of reaction

Question 2

Does a change in temperature affect all reactions?

Answer 2

It only affects endothermic reactions

Question 3

How does the Maxwell Boltzmann distribution graph change under higher temperatures?

Answer 3

Peak is further along and lower
Both have the same area which makes the peak lower
There is a larger number of molecules above the activation energy
