问题:

下列各组变化中,ΔH或Q前者小于后者的一组是(  )。

①CH4(g)+2O2(g)=CO2(g)+2H2O(l) ΔH1

CH4(g)+2O2(g)=CO2(g)+2H2O(g) ΔH2

②2H2(g)+O2(g)=2H2O(l) ΔH1

H2(g)+O2(g)=H2O(l) ΔH2

③t ℃时,在一定条件下,将1 mol SO2和1 mol O2分别置于恒容和恒压的两个密闭容器中,达到平衡状态时放出的热量分别为Q1、Q2

④CaCO3(s)=CaO(s)+CO2(g) ΔH1

CaO(s)+H2O(l)=Ca(OH)2(s) ΔH2

A.①②③

B.②④

C.②③④

D.③④
