Compound mn decomposes to form m and n in a reaction that is first-order with respect to mn and first order overall. the half-life for the reaction is 2.3 × 10^4 s. what is the rate constant of this reaction at 25°c? mn → m + n a) 3.0 × 10^3 s b) 1.6 × 10^(–4) s^(–1) c) 3.0 × 10^(–5) s^(–1) d) 3.3 × 10^(–4) s^(–1)

Explanation:

The reaction given follows this pattern:

1) Decomposition reaction:

2) First-order kinetic with respect to MN and first-order overall:

                               t = τ

 ∴ τ =  ln(2) / k ⇒ k = ln (2) / τ =  ln(2) / 2.3 × 10⁴ s / ln(2) = 3.0 × 10⁻⁵ s⁻¹
