反应N2(g) + 3H2(g) = 2NH3(g) 的ΔrHmӨ,298 = -92.2 kJ⋅mol-1,若升高温度,则 ΔrHmӨ (T)和ΔrSmӨ (T)怎么变化
举一反三
- 热化学方程式 N2(g)+3H2(g)=2NH3(g) ΔrHmӨ(298K) = -92.2 kJ·mol-1 表示
- 25℃时,反应N2(g) + 3H2(g) =2NH3(g),∆rHmӨ= -92.2kJ·mol-1,若升高温度,则
- 反应2NH3(g)= N2(g)+ H2(g), △rHmθ(298k)=92.2 kJ·mol-1则△fHmθ(NH3,g,298K)=____
- 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298 K 时反应 2 N2 (g) + O2 (g) = 2 N2O (g) 的Δ rUmΘ = 166.5 kJ · mol-1 , 则该反应的Δ rHmΘ 为
