Expert Answer

Step 1

The randomness and disorder of molecules in a given system which represent the different number of arrangements, is known as entropy of the system. The symbol of entropy is represented by the capital letter S.

Step 2

The change of entropy also happens in chemical reactions. In an exergonic chemical reaction, the energy of system is liberated, and entropy of the system also increases because the final products contain less energy inside them in order to attach their chemical bonds together. The entropy of the system's surroundings is considered escalate by this process.

Step 3

Since, ΔH is considered negative in an exothermic reaction, so, the entropy of the surroundings gives positive value which means entrop...
