ΔS0will be highest for the reaction:a)Ca(s)+1/2 O2 (g)→ CaO...
Explanation:
Reaction with the highest ΔS0:
- The reaction with the highest standard entropy change (ΔS0) is the one that involves the most significant change in the number of moles of gaseous substances between the reactants and products.
- In this case, the reaction CaCO3(s) → CaO(s) + CO2(g) involves the decomposition of one mole of solid CaCO3 into one mole of solid CaO and one mole of gaseous CO2.
- This results in an increase in the number of moles of gaseous substances from 0 to 1, leading to a greater disorder in the system and thus a higher standard entropy change.
Therefore, the reaction CaCO3(s) → CaO(s) + CO2(g) has the highest standard entropy change among the given options.
