2016年安徽省六安一中高考化学模拟试卷(三)
2H2(g)+O2(g)═2H2O(g)△H═﹣484KJ/mol
CH4(g)+2O2(g)═CO2(g)+2H2O(g)△H═﹣802KJ/mol
则:CH4(g)+CO2(g)⇌2CO(g)+2H2 (g)△H═.
CH2CH3(g) =CH2(g)+H2(g)△=+QkJ.mol﹣1
反应Ⅰ(主):CH3OH(g)+H2O(g) CO2(g)+3H2(g) △H1=+49 kJ/mol
反应Ⅱ(副):H2(g)+CO2(g) CO(g)+H2O(g) △H2
反应Ⅲ:CH3OH(g) CO(g)+2H2(g) △H3=+90kJ/mol
N2(g)+O2(g)=2NO(g);ΔH=+180 kJ·mol-1
则2CO(g)+2NO(g)=N2(g)+2CO2(g)的ΔH是( )
