Answer 27

ok

Answer 28

Let's look at rusting

when metal rusts, it is caused by oxygen and moisture in the air, hence this takes alot of time, and is a slow reaction

idk how fast photosynthesis works (speed of light??)

wood takes forever to rot

explosions have a high rate of energy, are are a series of fast chemical reactions. If you think of a bomb, it explodes very quickly and has alot of energy to give out, so I think this is your answer
