A．\(\rm{CH_{4}(g)+2O_{2}(g)=CO_{2}(g)+2H_{2}O(g)}\)；\(\rm{\triangle H=-890.3 kJ⋅mol^{-1}(}\)燃烧热\(\rm{)}\) |
|
B．同温同压下，反应\(\rm{H_{2}(g)+Cl_{2}(g)=2HCl(g)}\)在光照和点燃条件下的\(\rm{\triangle H}\)不同 |
|
C．\(\rm{CaCO_{3}(s)=CaO(s)+CO_{2}(g)}\)室温下不能自发进行，该反应的\(\rm{\triangle H > 0}\) |
|
D．已知：\(\rm{2C(s)+2O_{2}(g)=2CO_{2}(g) \triangle H_{1}}\)；\(\rm{2C(s)+O_{2}(g)=2CO(g) \triangle H_{2}}\)；则\(\rm{\triangle H_{1} < \triangle H_{2}}\) |
