*下列 反应的△rHmθ (298K)就是△fHmθ (CO2, g,298K)...CO2(g) = C(石墨)+O2(g)
举一反三
- *下列反应的△rHmθ(298K)就是△fHmθ(CO2,g,298K)。 (A)CO(g)1/2O2(g)=CO2(g)(B)C(金刚石)O2(g)=CO2(g) (C)C(石墨)O2(g)=CO2(g)(D)CO2(g)=C(石墨)O2(g)
- *下列 反应的△rHmθ (298K)就是△fHmθ (CO2, g,298K)...CO2(g) = C(石墨)+O2(g)
- *下列 反应的 △ r H m θ (298K) 就是 △ f H m θ (CO 2 , g,298K) 。 (A) CO(g)+1/2O 2 (g)=CO 2 (g) (B) C( 金刚石 )+O 2 (g)=CO 2 (g) (C) C( 石墨 )+O 2 (g)=CO 2 (g) (D) CO 2 (g) = C( 石墨 )+O 2 (g)
- 下列反应中表达式正确的是() A: Na(s)+1/2 Cl2 (g) = NaCl(s) ΔrHmθ=ΔfHmθ(NaCl,s) B: C(石墨) + H2(g) = 1/2 C2H4(g) ΔrHmθ=ΔfHmθ (C2H4,g) C: CO(g)+ 1/2 O2(g) = CO2(g) ΔrHmθ=ΔfHmθ (CO2,g) D: CH3OH(g) + O2(g) = CO (g) + 2H2O(g) ΔrHmθ=ΔcHmθ(CH3OH,g)
- 下列哪个反应的△rHmθ(298K)就是△fHmθ(CO2, g,298K)
