Question

The time required to decompose SO₂Cl₂ to half of it's initial amount is 60 minutes. Calculate rate constant for this first order reaction.

Options

• 4.158 × 10⁻² min⁻¹

• 2.651 × 10⁻² min⁻¹

• 1.155 × 10⁻² min⁻¹

• 1.551 × 10⁻² min⁻¹

Answer 1

1.155 × 10⁻² min⁻¹

Explanation:

t_1/2 = `0.693/"k"`

∴ k = `0.693/60`

= 1.155 × 10⁻² min⁻¹
