反应N2(g)+3H2(g)→2NH3(g)的[img=48x26]18031989fc1ba66.png[/img]与反应1/2N2(g)+3/2H2(g)→NH3(g)的[img=48x26]18031989fc1ba66.png[/img]相同
举一反三
- 298K时,N2(g)+3H2(g)=2NH3(g),△rHm(1)=-92.38kJ.mol-1,则1/2N2(g)+3/2H2(g)=NH3(g)△rHm(2)=()
- 已知下列反应N2(g) + 3H2(g) = 2NH3(g) (1)1/2N2(g) + 3/2H2(g) = NH3(g) (2) 1/3N2(g) + H2(g) = 2/3NH3(g) (3)的平衡常数分别为 Kθ1 、Kθ2 、Kθ3 ，则它们的关系是 A: Kθ1=Kθ2=Kθ3 B: Kθ1 = (Kθ2)2 = (Kθ3)3 C: Kθ1 =3/2Kθ2 =2/3Kθ3 D: Kθ1 = (Kθ2)1/2 = (Kθ3)1/3
- 反应N2(g) + 3H2(g) = 2NH3(g)的ΔG = a，则NH3(g) = 1/2N2(g) + 3/2H2(g)的ΔG为： ( ) A: a2 B: 1/a C: 1/ a2 D: –a/2
- 反应N2(g) + 3H2(g) = 2NH3(g)的△G = a，则NH3(g) = 1/2N2(g) + 3/2H2(g)的△G为： 未知类型：{'options': ['', '1/a', '', '－a/2'], 'type': 102}
- 已知下列反应的标准平衡常数：反应1：H2(g) + 1/2 O2(g) → H2O(g)，[img=27x26]1803aba487f13c8.png[/img]反应2：N2(g) + O2(g) → 2 NO(g)，[img=27x26]1803aba48f8667a.png[/img]反应3：2 NH3(g) + 5/2 O2(g) → 2 NO(g) + 3 H2O(g)，[img=27x26]1803aba497d60b7.png[/img]则反应：N2(g) + 3 H2(g) → 2 NH3(g)的标准平衡常数等于 A: [img=124x27]1803aba4a1122ec.png[/img] B: [img=146x27]1803aba4a98ffd1.png[/img] C: [img=103x26]1803aba4b180363.png[/img] D: [img=112x26]1803aba4bafa995.png[/img]
