A．已知甲烷的燃烧热为\(\rm{890.3kJ/mol}\)，则甲烷燃烧的热化学方程式可表示为\(\rm{CH_{4}(g)+2O_{2}(g)══ 2CO_{2}(g)+2H_{2}O(g)}\) \(\rm{ΔH = -890.3 kJ/mol}\) |
|
B．已知\(\rm{C(}\)石墨，\(\rm{s)══ C(}\)金刚石，\(\rm{s)}\) \(\rm{ΔH > 0}\)，则金刚石比石墨稳定 |
|
C．已知中和热为\(\rm{ΔH = -57.3 kJ/mol}\)，则\(\rm{1mol}\)稀硫酸和足量稀\(\rm{NaOH}\)溶液反应的反应热就是中和热 |
|
D．已知\(\rm{S(g)+O_{2}(g)══ SO_{2}(g)}\) \(\rm{ΔH_{1}}\)；\(\rm{S(s)+O_{2}(g)══SO_{2}(g)}\) \(\rm{ΔH_{2}}\)，则\(\rm{ΔH_{1} < ΔH_{2}}\) |
