请你写出298K时的下列反应的热化学方程式
(1)1mol C与1mol水蒸气反应生成l mol C0和lmol H
2,吸热131.5kJ
C(s)+H2O(g)=CO(g)+H2(g)△H=+131.5kJ/mol
C(s)+H2O(g)=CO(g)+H2(g)△H=+131.5kJ/mol
(2)用CO(g)还原l mol Fe
20
3(s),放热24.8kJ
3CO(g)+Fe2O3(s)=2Fe(s)+3CO2(g)△H=-24.8kJ/mol
3CO(g)+Fe2O3(s)=2Fe(s)+3CO2(g)△H=-24.8kJ/mol
(3)1mol HgO(s)分解生成液态汞和氧气时,吸热90.7kJ
HgO(s)=Hg(l)+
O
2(g)△H=+90.7kJ/mol
HgO(s)=Hg(l)+
O
2(g)△H=+90.7kJ/mol
(4)0.2mol 液态CS
2在O
2中完全燃烧,生成两种气态氧化物,放出热量218kJ
CS2(l)+3O2(g)=CO2(g)+2SO2(g)△H=-1075kJ/mol
CS2(l)+3O2(g)=CO2(g)+2SO2(g)△H=-1075kJ/mol
