Question 13

What happens to the shape of the maxwell-boltzman curves and the number of particles with Ea when you remove half the molecules?

Answer 13

Shape remains the same and exactly halves in the number of molecules.

Less particles with Ea

Question 14

What happens to the shape of the maxwell-boltzman curves and the number of particles with Ea when you add a catalyst?

Answer 14

Same shape

More particles with Ea

Question 15

What happens to the shape of the maxwell-boltzman curves and the number of particles with Ea when you reduce the volume of the container?

Answer 15

Same shape

Same number of particles with Ea
