Question

Which of the following statements is/are true? Select all that apply. a. The entropy of the starting materials for a reaction is always greater than the entropy of the products. b. The entropy of the products of a reaction is always greater than the entropy of the starting materials. c. The amount of useable energy resulting from a reaction is always less than the total energy available in the starting materials.d. The energy of the starting materials for a reaction equals the sum of the product energies plus energy released as heat and disorder.

Answer 1

Answer:

The entropy of the products of a reaction is always greater than the entropy of the starting materials

Explanation:

The second Law of Thermodynamics says that entropy always increases

A + B ----> AB

A and B that were completely arranged in their structures had to be completely messy to form compound AB

When an isolated system reaches a maximum entropy configuration, it can no longer undergo changes: it has reached equilibrium.
