During a chemical reaction, increasing the temperature often
a. reverses the direction of chemical change.
b. decreases the rate of chemical change.
c. increases the rate of chemical change.
od. prevents a chemical change from occurring.

c

Explanation:

the rate of reaction increases as temperature increases

b

explanation:

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
