Ответ:

дано

m(ZnS) = 271.6 kg

Vпр (SO2) = 58330 L

--------------

η(SO2) - ?

2ZnS + 3O2--2ZnO +2SO2

M(ZnS) = 97 kg/kmol

n(ZnS) = m/M = 271.6 / 97 = 2.8 kmol = 2800 mol

2n(ZnS) = 2n(SO2)

V теор (SO2) = n(SO2) * Vm = 28 00 * 22.4 = 62720 L

η(SO2 = Vпрак (SO2) / V теор (SO2) * 100% = 58330 / 62720 * 100% = 93%

ответ 93%
