Question 5 Which of the following is the reaction quotient expression for the ionization of NH3 in water? The equilibrium constant for the reaction of NH with water is 1.76x10-5. A Kb=[NH]/[OH-][NH₂] B Kb=[NH+a][NH_] +4 Kb= [OH-]/[NH₂] D Kb=[NH+] Question 6 B) Decreases 3 Points A necessary step in the manufacture of sulfuric acid is the formation of sulfur trioxide, SO₂, from sulfur dioxide, SO₂, and oxygen, O₂, shown here. At high temperatures, the rate of formation of SO₂ is higher, but the equilibrium amount (concentration or partial pressure) of SO is lower than it would be at lower temperatures. The balanced reaction equation is 2SO₂(g) + O₂(g) → 25O₂(g) . What does the equilibrium constant for this reaction do as the temperature increases? (A) Remains the same Increases (D) Resets 3 Points
