Question 13

Steep slope means on a ROR graph…

Answer 13

mean higher ROR

Question 14

A shallow slope on a ROR graph…

Answer 14

means a low ROR

Question 15

Collision theory

Answer 15

What the ROR depends on (Correct Orientation and enough energy [like the fair height minimum)

Question 16

Things that impact ROR

Answer 16

Surface Area, Temperature, Concentration (or the pressure of a gas) and/or catalyst.

Question 17

How does SA impact the ROR?

Answer 17

The ratio of the SA to Volume leads to more area in order to have more frequent collisions.
