Question

Which of the following is/are true regarding the half-life of any reaction? I. The half-life decreases as the reaction progresses II. The half-life decreases as the activation energy increases III. The half-life decreases as temperature increases I, II, and III II only II and III I only I and III I and II III only

Answer 1

option 2.

Step-by-step explanation:

The half-life of a reaction is the time it takes for half of the reactants to be consumed or the product to be formed. It is not affected by the progress of the reaction (I is false). The half-life generally decreases as the temperature increases (III is true) because higher temperatures provide more energy for molecules to collide and react. Activation energy doesn't directly influence the half-life; instead, it affects the reaction rate (II is false). Therefore, the correct option is "II only."
