The reaction is second-order, and the half-life for a second-order reaction is given by t₁/₂ = 1 / (k[A]₀). Using the given rate constant k = 7.22 × 10⁹ M⁻¹s⁻¹ and initial concentration [A]₀ = 0.0250 atm (converted to M using the ideal gas law), the half-life is calculated to be approximately 1.24 × 10⁷ s.
