Hope this helps you!!!

Answer 2

$\huge\mathfrak{\underline{\underline{Entropy}}}$

It is the measure of degree of randomness or disorderness in an isolated system and is represented by the symbol S. The greater the degree of randomness, higher is the entropy. In case of chemical reactions, it shows the rearrangement of atoms or ions from one pattern in the reactants to another (in the products). If the structure of product is more disordered as compared to reactants, entropy of the reaction increases and if the structure of reactant is more disordered as compared to products, it results in decreased entropy.
