Step 1:
C2H6 (g) + 7/2 O2 (g) → 2 CO2 (g) + 3 H2O (g)
Reactant Product
C 2 1 2
H 6 2 6
O 2 7 3 7
Balanced chemical equation
2 C2H6 (g) + 7 O2 (g) → 4 CO2 (g) + 6 H2O (g)
9 mol gas reactant → 10 mol gas reactant
increase in entropy
sign of ΔS should be positive
Step 2:
Find ΔS°rxn for the combustion of ethane (C2H6) to carbon dioxide and gaseous water. Is the sign of ΔS°rxn as expected?
