Sulfur Trioxide Can Undergo Decomposition According to the Equation \rightarrow 2SO2 + O2
for This Reaction, Rate = -0 0

Question 11

Multiple Choice

Sulfur trioxide can undergo decomposition according to the equation
2SO3 \rightarrow 2SO2 + O2
For this reaction, rate = -0 0.5 Δ\Delta [SO3]/ Δ\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
