Question

a.cate kg de sulf sunt necesare pt a produce arderea a 64kg de SO2? b.cate kg de SO2 sunt necerare pt obtine a 80kg de SO3? c.cate kg de sulf sunt necesare pt a obtine 98kg de acid sulfuric?

Answer 1

128kg......96kg....32kg
2SO2 --> 2SO + O2
64kg......x=48kg...y=16kg
MSO=48kg/kmol

n=m/M=48/96=0.5 Kmoli SO

mS=n*M=0.5*32=16Kg Sulf

160kg......128kg....32kg
2SO3 --> 2SO2 + O2
90kg..........x=72kg

MSO2=64kg/kmol

n=m/M=72/64=1.125 kmoli SO2

mS=n*M=1.125*32=36 kg Sulf

98kg...........80kg
H2SO4 --> SO3 + H2O
98kg............80kg

MSO3=80kg/kmol

n=m/M=80/80=1 kmol SO3


mS=n*M=1*32=32kg Sulf
