transformam V de CH₄ in moli
n=V/Vs=4032/22,4=180moli
pornim de la 100moli amestec
in 100moli amestec..........15moli acetilena......45moli H₂ (stoechiometric necesar).......40moli CH₄ nereactionat
2moli.....1mol....3moli
2CH₄ -> C₂H₂ + 3H₂
30moli 15moli 45moli
1mol 1mol
CH₄ -> CH₄
40moli 40moli
100moli amestec.......15moli acetilena.......70moli CH₄ introdus
xmoli acetilena.......180moli CH₄ introdus
x=15*180/70 si nu efectuam
Vacetilena=n*Vm=15*180*22,4/70=864l acetilena
