The entropy change of a reaction where the reactants and products are in their standard state can be determined using the following equation:
ΔS⁰ = ∑nS⁰(products) – ∑mS⁰(reactants)
where n and m are the coefficients found in the balanced chemical equation of the reaction.
Example 1
Determine the change in the standard entropy, ΔS⁰, for the synthesis of carbon dioxide from graphite and oxygen:
C(s) + O2(g) → CO2(g)
Solution
ΔS⁰ = ∑nS⁰(products) – ∑mS⁰(reactants)
ΔS⁰ = (213.8 J/mol K) – (205.2 J/mol K + 5.7 J/mol K)
ΔS⁰ = +2.9 J/mol K
