Question

For each of the scenarios, identify the order with respect to the reactant, A. A⟶products The half‑life of A increases as the initial concentration of A decreases. order: A three‑fold increase in the initial concentration of A leads to a nine‑fold increase in the initial rate. order: A three‑fold increase in the initial concentration of A leads to a 1.73‑fold increase in the initial rate. order: The time required for [A] to decrease from [A]0 to [A]0/2 is equal to the time required for [A] to decrease from [A]0/2 to [A]0/4. order: The rate of decrease of [A] is a constant. order:

Answer 1

Answer:

Answers are in the explanation.

Explanation:

• The half‑life of A increases as the initial concentration of A decreases. order: 2. In the half-life of second-order reactions, the half-life is inversely proportional to initial concentration.
• A three‑fold increase in the initial concentration of A leads to a nine‑fold increase in the initial rate. order: 2. The rate law of second-order is: rate = k[A]²
• A three‑fold increase in the initial concentration of A leads to a 1.73‑fold increase in the initial rate. order: 1/2. The rate law for this reaction is: rate = k √[A]
• The time required for [A] to decrease from [A]₀ to [A]₀/2 is equal to the time required for [A] to decrease from [A]₀/2 to [A]₀/4. order: 1. The concentration-time equation for first-order reaction is: ln[A] = ln[A]₀ - kt. That means the [A] decreasing logarithmically.
• The rate of decrease of [A] is a constant. order: 0. The rate law is: rate = k -where k is a constant-
