Boltzmann distrubution

Question 1

How do you draw a Boltzmann distribution curve?

Answer 1

Number of particles on your axis, line starts at origin, curve doesn’t touch x axis and allies line through curve labelled Ea

Question 2

What does the peak represent?

Answer 2

The modal energy

Question 3

What does the area under the curve represent?

Answer 3

The total number of particles

Question 4

What are the particles after the Ea line?

Answer 4

They have energy equal to or greater than Ea so can react on collision

Question 5

How do you draw a higher and lower T curve?

Answer 5

The lower T has a high peak which is more to the left and the high T has a lower peak further to the right and line remains above the lower T, including at the end

Question 6

What is the modal temperature at a high T?

Answer 6

It is higher

Question 7

What stays the same across temperatures?

Answer 7

The area under the curve

Question 8

What is the difference with particles after Ea at different temps?

Answer 8

The area under the lower temp can react at a lower T and those between higher and lower are extra particles than react at a higher T

Question 9

How do you draw a Boltzmann curve with a catalyst?

Answer 9

There is a higher up Ec line of the activation energy due to catalyst

Question 10

What is the effect of a catalyst on the graph?

Answer 10

Those after Ec has enough energy on collision so a greater proportion of collisions with result in reactions
