已知:H2(g)+1/2O2(g)=H2O(g)焓变为负241.8KJ.mol,该反应的活化能为167.2KJ.MOL,
已知:H2(g)+1/2O2(g)=H2O(g)焓变为负241.8KJ.mol,该反应的活化能为167.2KJ.MOL,
已知:H2O(g)的标准摩尔生成焓Δ ,为-241.82kJ/mol,则反应2H2(g)+O2(g)=2H2O(g)的Δ
已知2H2(g)+O2(g)==2H2O(g) 则 H=-483.6kJ/mol ,则氢气的燃烧热为241.8KJ/mo
1mol水蒸气转化为液态水放出45KJ,则H2(g)+1/2 O2(g)=H2O(g)△H= kj/mol.氢气的燃烧热
已知H2(g)+1/2O2(g) =H2O(g)H=-241.8kj/mol 下列说法不正确的是 A H2然烧放出的热量
已知(1)2H2(g)+O2(g)=2H2O(g) △H=-483.6kJ.mol-1
已知热化学方程式:H2O(g)=H2(g) O2(g) △H= 241.8kJ·mol-1; H2(g) O2(g)=H
大学工程化学题反应2 SO2(g)+O2(g)=2 SO3(g)的活化能为251.0kj/mol,在pt催化下活化能降为
已知2H2(g)+O2=2H2O(l)△H=-571.6kJ/mol,CO(g)+1/2O2(g)=-285.8kJ/m
化学H2(g)+2/1O2(g)==H2O(g)△H1=-241.8kj/mol
已知H2+1/2O2=H2O(l) 焓变= -285.83KJ/mol,CO(g)+1/2O2(g)=CO2(g) 焓变
H2(g)+1/2O2(g)==H2O(g) △H=+242KJ/mol , 2H2(g)+O2(g)==2H2O(g)
