The following reaction is first order,C₂H₆ → 2 CH₃.If the rate constant is equal to 5.5 × 10^-4 s^-1 at 1000 K,how long will it take for 0.35 mol of C₂H₆ in a 1.00 L container to decrease to 0.25 mol in the same container?

For a first-order reaction, the time can be calculated using the formula: t = (1/k) * ln([A]₀/[A]). Substituting the given values: k = 5.5 × 10⁻⁴ s⁻¹, [A]₀ = 0.35 mol/L, [A] = 0.25 mol/L, we find t ≈ 600 seconds, which is 10 minutes.
