Entropy is a measure of the randomness of the system. The entropy change in a chemical reaction can be calculated by measuring the number of moles of gaseous reactants and products.The solid substances have the minimum disorder, hence the entropy of the solid is minimum. The disorder of the liquid is higher than the solid, hence the entropy of the liquid is higher than the solid. The entropy of the gaseous substance is the highest because the disorder in the gaseous substance is the greatest.Hence the entropy of the different states of matter is as follows: Sgas > Sliquid > SsolidLet us use the equation, The sign of reaction entropy for the given reactions is as follows:1) Here, product has only one aqueous state and reactant has two aqueous state . Since, Sgas > Sliquid Then, 2) Only the reactant has a gaseous state. So, 3) Here, only the reactant has a gaseous state.so, Therefore,
