For a first-order reaction, the half-life is independent of which of the following?

For a first-order reaction, the half-life is independent of which of the following?

Correct Answer: initial concentration

Step 1: Understand what a first-order reaction is. It is a type of chemical reaction where the rate depends on the concentration of one reactant.
Step 2: Learn about half-life. The half-life is the time it takes for half of the reactant to be used up in the reaction.
Step 3: Recognize that for first-order reactions, the half-life is a constant value. This means it does not change over time.
Step 4: Identify what the half-life depends on. For first-order reactions, it depends on the rate constant, not the initial concentration of the reactant.
Step 5: Conclude that the half-life is independent of the initial concentration of the reactant in a first-order reaction.

First-Order Reactions – In first-order reactions, the rate of reaction is directly proportional to the concentration of one reactant, and the half-life remains constant regardless of the initial concentration.
Half-Life – The half-life of a reaction is the time required for the concentration of a reactant to decrease to half its initial value.
