Answer :
Final answer:
The standard entropy change (ΔS°) for a reaction can be calculated using the standard entropies (S°) of the reactants and products. By subtracting the sum of the standard entropies of the reactants from the sum of the standard entropies of the products, we can find the entropy change.
Explanation:
The standard entropy change (ΔS°) for a reaction can be calculated using the standard entropies (S°) of the reactants and products. By subtracting the sum of the standard entropies of the reactants from the sum of the standard entropies of the products, we can find the entropy change.
For the given reaction, H₂(g) + C₂H₂(g) → C₂H₆(l), we need to find the standard entropies of the reactants and products. Using thermodynamic data at 298 K, we can find the standard entropy values from tables or databases.
Once we have the standard entropies for H₂(g), C₂H₂(g), and C₂H₆(l), we can calculate the entropy change for the reaction.
