1

At ordinary temperatures, how does increasing the temp by 10* affect the rate of reaction?

It double the number of reactions in a given time

2

At ordinary temperatures, how does decreasing the temp by 10* affect the rate of reaction?

It halves the number of reactions in a given time.

3

Why does a small change in temp have a large effect on the rate of reaction?

It increases the frequency of collisions and the energy of the particles

4

What does a higher temperature bring to the rate of reaction? Why?

It brings a more energy for the particles in the reaction so they move faster and collide more often and with more energy which both increase the rate of reaction
