举一反三
- 下列过程中,∆G = ∆A的是: A: H2O(l,373K,p)®H2O(g,373K,p) B: N2(g,400K,1000kPa) ®N2(g,400K,100kPa) C: 等温等压下,N2(g) + 3H2(g)®NH3(g) D: Ar(g,T,p) ®Ar(g,T+100K,p)
- △G=△A的过程是:() A: H2O(l,373K,p)→H2O(g,373K,p); B: N2(g,400K,1000kPa)→N2(g,400K,100kPa); C: 等温等压下,N2(g)+3H2(g)→NH3(g); D: Ar(g,T,p)→Ar(g,T+100,p)。
- ∆G = ∆A的过程是 A: H2O(l,373K,p)→H2O(g,373K,p) B: N2(g,400K,1000kPa)→N2(g,400K,100kPa) C: 等温等压下,N2(g) + 3H2(g) → 2NH3(g) D: Ar(g,T,p) →Ar(g,T+100,p)
- △G=△A的过程是:() A: HO(l,373K,p)→HO(g,373K,p); B: N(g,400K,1000kPa)→N(g,400K,100kPa); C: 等温等压下,N(g)+3H(g)→NH(g); D: Ar(g,T,p)→Ar(g,T+100,p)。
- 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
