Consider the following first-order decomposition reaction: A4(g) → 4A(g). Which of the following sta — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Intersection at t=30 min: [A4]=[A] => A0 e^-kt = 4A0(1-e^-kt) => e^-kt = 0.8 => k = 0.00743 min⁻¹. t_1/2 = 93 min ≈ 90 min. Reaction at 30 min = 1-0.8 = 20%. Intersection time independent of A0.
