下列反应中，Q₂>Q₁的是           (　　)

A．H2(g)＋F2(g)=2HF(g)　ΔH＝－Q1 kJ·mol^－1 H2(g)＋Cl2(g)=2HCl(g)　ΔH＝－Q2 kJ·mol^－1

B．2H2(g)＋O2(g)=2H2O(l)　ΔH＝－Q1 kJ·mol^－^1 2H2(g)＋O2(g)=2H2O(g)　ΔH＝－Q2 kJ·mol^－^1

C．NaOH(aq)＋HCl(aq)=NaCl(aq)＋H2O(l)ΔH＝－Q1 kJ·mol^－^1 NaOH(aq)＋CH3COOH(aq)=CH3COONa(aq)＋H2O(l)ΔH＝－Q2 kJ·mol^－^1

D．S(s)＋O2(g)=SO2(g)　ΔH＝－Q1 kJ·mol^－^1

S(g)＋O₂(g)=SO₂(g)　ΔH＝－Q₂ kJ·mol^－1
