Most of the sulfur used in the United States is chemically synthesized from hydrogen sulfide gas recovered from natural gas well
Rom4ik [11]

Answer:

The rate at which sulfur dioxide is being produced is 0.90 kg/s.

Explanation:

Volume of oxygen gas consumed in second ,V= 994 L

Pressure of the gas = p

Temperature of the gas = T = 170°C= 170 + 273 K=443 K

Moles of oxygen gas consumed in a second = n

PV=nRT ( ideapl gas equation)

n=\frac{PV}{RT}=\frac{0.77 atm\times 994 L}{0.0821 atm L/mol K\times 443 K}

n = 21.044 mole

Moles of dioxygen gas consumed per second = 21.044 mol

2H_2S(g)+3O_2(g)\rightarrow 2SO_2(g)+2H_2O(g)   (Claus process)

According to reaction, 3 moles of dioxygen gives 2 moles of sulfur dioxide gas.Then 21.044 moles of dioxygen will give;

\frac{2}{3}\times 21.044 ol=14.029 mol of sulfur dioxide

Mass of 14.029 moles of sulfur dioxide gas;

14.029 mol × 64 g/mol = 897.86 g

897.86 g = 0.89786 kg ≈ 0.90 kg

Mass of sulfur dioxide produced per second = 0.90 kg

The rate at which sulfur dioxide is being produced is 0.90 kg/s.
