Rate Of Reactions

Question 1

Describe the Boltzmann distribution curve when temperature increases

Answer 1

When temp increases the peak drops and shifts to the right

Question 2

Describe the Boltzmann distribution curve when temperature decreases

Answer 2

When temp decreases the peak increases and shifts to the left

Question 3

Describe the Boltzmann distribution curve when catalyst is added

Answer 3

The Ea line shifts to the left

Question 4

What is activation energy

Answer 4

Is the minimum energy that colliding particles must possess for a successful collision to take place

Question 5

Explain the term rate of a reaction

Answer 5

Rate =change in the amounts of products or reactants /time

Question 6

State the collision theory

Answer 6

For a successful collision to take place particles must collide in the correct orientation and must have sufficient energy

Question 7

According to the Collision theory, a rxn will speed up if

Answer 7

a) the frequency of collision increases

b) the proportion of particles with energy > activation energy increases
