What is the entropy change if 4.50 g of CaCO₃(s)is placed in a container and allowed to decompose to CaO(s)and CO₂(g)according to the following reaction? CaCO₃(s)$\leftrightarrows$CaO(s)+ CO₂(g)

Question

Quizplus · Accepted Answer

The entropy change for the reaction can be calculated using the following equation:ΔS = ΣS°(products) - ΣS°(reactants)ΔS = [S°(CaO) + S°(CO2)] - [S°(CaCO3)]ΔS = [(39.75 J/mol K) + (213.6 J/mol K)] - [92.88 J/mol K]ΔS = +7.22 J/K
