You would like to set up a business to reduce atmospheric SO2(g) using the reaction: 8 SO2 (g) + heat <--> S8 (g) + 8O2 (g)

1. State three different ways you could make this reaction more effective.

2. Explain why one of the ways you gave above might not be cost effective.

Solutions

Expert Solution

According to Lechatlier's principle for an endothermic reaction (heat absorbing reaction)

(a) Increasing temperature could make this reaction more effective.

(b) Introducing a catlayst oxygen-deficient ferrite (Fe₃O_4-Â¿) or Pt/CeO₂ could make this reaction more effective.

(c) As product moles (1 + 8 = 9) are higher than reactant moles (8) hence reducing pressure could make this reaction more effective.

2. Using a catalyst (regenerative chemical is called as catalyst after completion of reaction) decreases the activation energy so that the reaction can be in progress under low temperatures also, this will reduce cost for production of thermal energy and also reaction will go faster (less time required compare to without catalyst), saves time and money.

The quantity of atmospheric SO2(g) can be determined by reaction with H2O2(aq) The amount of sulfuric acid produced can be determined by titration with sodium hydroxide of known concentration. An 571.0 gram sample of an air that is known to contain sulfur dioxide was reacted with excess hydrogen peroxide. Given that 18.50 mL of a 0.00250 M NaOH(aq) were required to neutralize the H2SO4(aq) produced, calculate the mass percentage of SO2(g) in the air sample.

The reaction SO2(g)+2H2S(g)←−→3S(s)+2H2O(g) is the basis of a suggested method for removal of SO2 from power-plant stack gases. The standard free energy of each substance are ΔG∘fS(s) = 0 kJ/mol, ΔG∘fH2O(g) = -228.57 kJ/mol, ΔG∘fSO2(g) = -300.4 kJ/mol, ΔG∘fH2S(g) = -33.01 kJ/mol.
