Read the Assertion and Reason below and choose the correct option. — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

The temperature coefficient of a single-step (elementary) reaction is always positive because the rate constant invariably increases with an increase in temperature (positive activation energy). The reason statement is correct because a negative order implies the concentration term is in the denominator of the rate law, reducing the rate as concentration increases. Therefore, correct answer is D.
