alleryTime required to decompose SO₂Cl₂ to half of its initial amount is 60 min. Assuming first-order kinetics, the rate constant is:
A60 min⁻¹
B0.0116 min⁻¹
C1.16 min⁻¹
D0.116 min⁻¹
Answer & Solution
Correct answer: B. 0.0116 min⁻¹
First-order: k = 0.693 / t_(1/2) = 0.693 / 60 = **0.01155 min⁻¹ ≈ 0.0116 min⁻¹**.
