for This Reaction, Rate = -0 0

question 10

Multiple Choice

Sulfur trioxide can undergo decomposition according to the equation
2SO₃ $\rightarrow$ 2SO₂ + O₂
For this reaction, rate = -0 0.5 $\Delta$ [SO₃]/ $\Delta$ t = k[SO₃]². If the reaction rate is 1.75 *10¯⁷ mol L¯¹ min¯¹ when the concentration of sulfur trioxide is 5.4 * 10¯³ mol L¯¹, what is the value of the rate constant k?

• A) 3.2 * 10¯⁵ L mol¯¹ min¯¹
• B) 1.6 *10¯⁵ L mol¯¹ min¯¹
• C) 6.0 * 10¯³ L mol¯¹ min¯¹
• D) 3.0 * 10¯³ L mol¯¹ min¯¹
• E) 1.6 * 10¯² L mol¯¹ min¯¹
