What is a consequence of the second law of thermodynamics?
- activation energy from the environment is required for every energy transfer.
- energy cannot be created or destroyed but it can be transferred.
- if there is an entropy decrease in the universe, there must be an increase in the entropy of a system.
- increases in the entropy of the universe are the result of chemical reactions.

Increase in the entropy of the universe are the result of chemical reactions

Explanation:

The second law tells about the quality of energy such that any isolated system tends to become more disordered. Any natural Process occurring on its own is irreversible and entropy is increasing for that process.  

The entropy of the Universe is increasing which is the result of chemical reactions. Any chemical reaction which increases the number of gas molecules will generate more entropy. Entropy in simple meaning is the order of randomness.
