Question HLPaper 1AAnswerWhich system has the most negative entropy change, ΔSΔSΔS, for the forward reaction?AN2(g)+3H2(g)⇌2NH3(g)N_2(g) + 3H_2(g) ⇌ 2NH_3(g)N2(g)+3H2(g)⇌2NH3(g)B2S2O32−(aq)+I2(aq)→S4O62−(aq)+2I–(aq)2S_2O_3^{2−}(aq) + I_2(aq) → S_4O_6^{2−}(aq) + 2I^–(aq)2S2O32−(aq)+I2(aq)→S4O62−(aq)+2I–(aq)CH2O(l)→H2O(g)H_2O(l) → H_2O(g)H2O(l)→H2O(g)DCaCO3(s)→CaO(s)+CO2(g)CaCO_3(s) → CaO(s) + CO_2(g)CaCO3(s)→CaO(s)+CO2(g)
