Step 1

Entropy (S) is a measure of the disorder or randomness in a system. For a reaction, ΔS° > 0 indicates that the disorder of the system increases during the reaction. Step 2: Analyze each reaction to determine the change in entropy. Show more…

For which of the following reactions is ΔS° > 0 at 25°C? MgO(s) + CO2(g) → MgCO3(s) 2CO(g) + O2(g) → 2CO2(g) F3BNH3(s) → BF3(g) + NH3(g) 2H2(g) + O2(l) → 2H2O(l) 2Li(s) + O2(g) → Li2O(s)
