Final answer:
Entropy is a measure of the randomness or disorder within a system. In chemical reactions, the total entropy of the system tends to increase. Chemical reactions generally favor high entropy.
Step-by-step explanation:
Entropy is a measure of the randomness or disorder within a system. It is the tendency of a system to proceed towards a state of greater disorder or randomness. In chemical reactions, the total entropy of the system tends to increase.
For example, entropy increases when molecules at a high concentration in one place diffuse and spread out. This is because the molecules become more randomly distributed, leading to higher entropy. Therefore, chemical reactions generally favor high entropy.
