Answer:
Decreasing temperature decreases the energy of the molecules. The molecules collide less, resulting in fewer reactions. When we cool our food to preserve it, we are slowing down reaction rates.

Answer:
Less energy to provide to molecules, fewer molecules reach activation energy.
Explanation:
Food cam go off due to different chemicals reacting with, or colliding with other molecules, in the food. Molecules have to collide with a minimum amount of energy, the activation energy or Ea. The lower the temperature, the less energy the molecules have, and the slower they therefore go. A fridge provides quite low temperatures, meaning fewer molecules have Ea
or higher. As there are fewer molecules to create a reaction, the food is kept fresher.
