Half-life of a reversible reaction may be defined as the time in which half of the amount of reactan — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Half-life defined this way is t_1/2 = ln(2) / (K_f + K_b). From our integration in the first subquestion, we established ln(2) = (K_f + K_b) × 10, thus t_1/2 = 10 min. Therefore, correct answer is A.
