Question

Time required to decompose SO₂Cl₂ to half of its initial concentration is 60 minutes. If the de-composite is a first order reaction, calculated the rate constant of the reaction-

Options

• 1.925 × 10^–4 sec^–1

• 2.623 × 10^–3 sec^–1

• 4 × 10^–4 sec^–1

• 2.1 × 10^–6 sec^–1

Answer 1

1.925 × 10^–4 sec^–1 

Explanation:

For the first-order reaction

Rate constant (k) = `0.693/(t_(1/2)) = 0.693/(60  "mi")`

= `0.693/(605 xx 605)`

= 1.925 × 10^–4 sec^–1
