nNH3 = 1700\17 = 100 mol
N2 + 3H2 --to--> 2NH3
50----------150 -------------- 100 (mol)
vì H =25%
⇒ nN2 = 50/H = 50/25% = 200 mol
⇒ mN2 = 200.28 = 5600 gam
⇒ nH2 = 150/H = 150/25% = 600 mol
⇒ mH2 = 600.2 = 1200 gam
nNH3=1700/17=100mol
PTHH: NN+3H2->2NH3
100/2<-100.3/2<-100
Theo pthh có nN2 =50 mol
mN2( cần dùng )=50.28.100/25=5600g
Theo pthh nH2= 150mol
mH2(cần dùng)=150.2.100/25=1200g
\(n_{NH3}=\frac{1700}{17}=100\left(mol\right)\)
PTHH:
\(N_2+3H_2->2NH3\)
(mol) 50 150 100
Theo PTHH:
\(\left\{{}\begin{matrix}n_{H2pư}=\frac{3}{2}\cdot n_{NH3}=\frac{3}{2}\cdot100=150\left(mol\right)\\n_{N2pư}=\frac{1}{2}\cdot n_{NH3}=\frac{1}{2}\cdot100=50\left(mol\right)\end{matrix}\right.\\ \Rightarrow\left\{{}\begin{matrix}n_{H2pư}=150\cdot2=300\left(g\right)\\n_{N2pư}=50\cdot28=1400\left(g\right)\end{matrix}\right.\\ \Rightarrow\left\{{}\begin{matrix}n_{H2}=300\cdot\frac{100}{25}=1200\left(g\right)\\n_{N2}=1400\cdot\frac{100}{25}=5600\left(g\right)\end{matrix}\right.\)
Vậy ...
