Sulfur dioxide is a significant air pollutant, especially from coal-fired power-plants. The following reaction is the basis of a suggested method for removal of SO2 from power-plant exhaust gases. Is this reaction a feasible method of removing SO2? Why or why not? Support your answer using the provided thermodynamic data. SO2(g) + 2H2S(g) → 3S(s) + 2H2O (g) ΔG° = -90.5 kJ ΔH° = -146 kJ ΔS° = -186 J/K
Sulfur dioxide reacts with carbon dioxide to form an equilibrium with sulfur trioxide and carbon monoxide, all gases (see the reaction below).
Sulfur dioxide reacts with carbon dioxide to form an equilibrium with sulfur trioxide and carbon monoxide, all gases (see the reaction below). A mixture of 1.81 mole each of sulfur dioxide and carbon dioxide is placed in an 2.1 L container and allowed to reach equilibrium. If the equilibrium constant, Kc, is 1.21 at this temperature, what is the concentration of sulfur trioxide at equilibrium? SO2 (g) + CO2 (g) ⇌ SO3 (2)+ CO (g) Keep extra significant figures during the calculation and...

1. In the gas phase, sulfur dioxide reacts with oxygen to form sulfur trioxide, 2502 + O2 = 2503. An equilibrium mixture at 1000K and 1767 torr had the following mole fractions: x(SO2) = 0.310, x(O2) = 0.250. SO3 was also present. Calculate Koº and AG° at 1000K, assuming all gases behave ideally.

Scientists determine the quantity of atmospheric sulfur dioxide (SO2), a large contributor to acid rain, by an indirect titration. First, a scientist collects a sample of air and reacts it with hydrogen peroxide (H,O,) to form a solution of sulfuric acid ( H, SO2). Then, the amount of H, SO, produced is determined by titration with a sodium hydroxide solution (NaOH) of known concentration. H,02(aq) + SO2(g) → H, 50,(aq) H, SO (aq) + 2NaOH(aq) + 2 H2O(l) + Na,...

Use the References to access important values if needed for this question A typical coal-fired electric generating plant will burn about 3 metric tons of coal per hour. Most of the coal burned in the United States contains 1 to 4 % by weight sulfur in the form of pyrite, which is oxidized as the coal burns: 4FeS2(s)+11 02(g)-2 FezO3(s)+ 8 SO2 Once in the atmosphere, the SO2 is oxidized to SO3, which then reacts with water in the atmosphere...

QUESTION 12 Sulfur dioxide gas contributes to acid rain. The concentration of SO2(g) in air can be determined by dissolving the SO2(g) in water and then titrating the solution produced with a standard solution of potassium permanganate, KMNO4(aq). If a 150 mL sample of SO2(aq) required 31.5 mL of 0.0100 mol/L of KMnO4(aq) to react, what is the concentration of SO2(aq) in the sample? (5 marks) The unbalanced reaction is: SO2(g) + MnO4 (aq) → S042 (aq) + Mn2+(aq) TTT...

Price of electricity Demand QQ4 Quantity of electricity Coal burning utilities release sulfur dioxide and nitric acid which react with water to produce acid rain. Acid rain damages trees and crops and kills fish. Because the utilities do not bear the cost of the acid rain, they overproduce the quantity of electricity. This is illustrated in the Figure above.
