Question

PCl₅ decomposes to PCl₃ and Cl₂ in a gas-phase reaction at 200 °C: PCl₅(g) → PCl₃(g) + Cl₂(g)
The following data were obtained for the reaction:

Calculate the rate of the reaction at the following concentrations: 0.150 M, 0.200 M, and 0.230 M.

Accepted Answer

Rate(0.150 M) = 3.87×10⁻⁴ M/s
Rate(0.200 M) = 5.16×10⁻⁴ M/s
Rate(0.230 M) = 5.93×10⁻⁴ M/s

Answer

Rate(0.150 M) = 4.12×10⁻⁴ M/s
Rate(0.200 M) = 3.16×10⁻³ M/s
Rate(0.230 M) = 2.85×10⁻³ M/s

Answer

Rate(0.150 M) = 8.44×10⁻⁵ M/s
Rate(0.200 M) = 9.25×10⁻⁴ M/s
Rate(0.230 M) = 1.15×10⁻³ M/s

Answer

Rate(0.150 M) = 4.56×10⁻³ M/s
Rate(0.200 M) = 8.22×10⁻² M/s
Rate(0.230 M) = 9.35×10⁻² M/s
