The half-life of a first-order reaction is dependent on which of the following?
Correct Answer: Rate constant (k)
- 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: Know the formula for half-life in a first-order reaction, which is t1/2 = 0.693/k.
- Step 4: Identify the components of the formula. Here, 't1/2' is the half-life, and 'k' is the rate constant of the reaction.
- Step 5: Realize that the half-life (t1/2) only depends on the rate constant (k) and not on the initial concentration of the reactant.
