Sulfur Trioxide Can Undergo Decomposition According to the Equation 2SO3

question 13

Multiple Choice

Sulfur trioxide can undergo decomposition according to the equation 2SO3 → 2SO2 + O2
For this reaction, rate = -0.5Δ[SO3 ]/Δt = 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?
