中国大学MOOC:对于反应N2(g)+3H2(g)=2NH3来说,△rHm和△rUm的关系为:
举一反三
- 对于反应N2(g) + 3H2(g) = 2NH3(g)来说,△rHm和△rUm的关系为: A: △rUm =△rHm + 2RT B: △rUm =△rHm - 2RT C: △rHm =△rUm + RT D: △rHm =△rUm + 2RT
- 对于反应N2(g) + 3H2(g) = 2NH3来说,△rHm和△rUm的关系为: A: △rUm =△rHm + 2RT B: △rUm =△rHm - 2RT C: △rHm =△rUm + RT D: △rHm =△rUm - RT
- 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)=()
- N2(g) + 3H2(g) = 2NH3(g)中N2、H2、NH3的化学计量数分别为( ) A: 1, 3, 2 B: -1, -3, 2 C: 1, 3, -2 D: -1, -3, -2
- 中国大学MOOC: 反应3H2(g)+N2(g)2NH3(g)的标准平衡常数为K,则反应H2(g)+N2(g)NH3(g)的标准平衡常数为(K)1/2。
