Question

What is the formula for calculating standard entropy change for a reaction?
Options
A ΔS°_rxn = Σ S°_products - Σ S°_reactants
Correct Answer
B ΔS°_rxn = Σ S°_reactants - Σ S°_products
C ΔS°_rxn = Σ S°_products + Σ S°_reactants
D ΔS°_rxn = (Σ S°_products) / (Σ S°_reactants)
Correct Answer

Option A is the correct answer.

Detailed Explanation

For a reaction, the standard entropy change is ΔS°_rxn = Σ n_i S°_products - Σ n_j S°_reactants, where n are stoichiometric coefficients and S° are standard molar entropies.

Hint

The notes provide this formula.
