1.	∆S is expected to be maximum for the reaction (a) Ca(s) + O(g) → CaO(S) (b) C(s) + O2(g) → CO2(g) (c) N2(g) + O2(g) → 2NO(g) (d) CaCO3(s) → CaO(s) + CO2(g)
Answer» (d) CaCO_3(s) → CaO_(s) + CO_2(g) In CaCO_3(s) → CaO_(s) + CO_2(g) entropy change is positive in (a) and (b) entropy change is negative; in (c) entropy change is zero.

∆S is expected to be maximum for the reaction (a) Ca(s) + O(g) → CaO(S) (b) C(s) + O2(g) → CO2(g) (c) N2(g) + O2(g) → 2NO(g) (d) CaCO3(s) → CaO(s) + CO2(g)

Answer»

(d) CaCO_3(s) → CaO_(s) + CO_2(g)

In CaCO_3(s) → CaO_(s) + CO_2(g) entropy change is positive in (a) and (b) entropy change is negative; in (c) entropy change is zero.
