If the temperature is increased, then — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

Since Ea1 (12 kcal/mol) > Ea2 (9 kcal/mol), the rate constant K1 has a higher temperature coefficient than K2. As temperature increases, both rates increase, but K1 increases faster, so the ratio K1/K2 (Y/Z) increases. Therefore, correct answer is D.
