What is the order of the reaction for each of the paths? — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Since the product ratio (10% B, 90% C) is constant and independent of the extent of reaction, the parallel paths must have the same kinetic order as the overall disappearance of A. Since A decomposes via first-order kinetics, both parallel paths must also be first-order. Therefore, correct answer is C.
