Based on this information what is the most likely reason for refrigerating most foods reduce the rate at which they spoil

The lower temperature reduces molecule speeds, reducing the number of effective collisions.

Explanation:

As the pickle jar was placed inside the refrigerator so, due to the decrease in temperature of the refrigerator the lid faced contraction in size.

As a result, it became tightly fitted over the mouth of the jar.

But when the lid was held under the hot water from your sink's faucet for a few seconds, then it undergoes a thermal expansion.

As a result, size of lid expanded as compared to the size of mouth of the jar. Hence, the lid is able to be opened up.
