What is the half-life of a reaction?

Options

  1. AThe time it takes for the reaction to reach completion
  2. BThe time it takes for the concentration of a reactant to become zero
  3. CThe time it takes for the concentration of a reactant to become half of its initial concentration
  4. DThe time it takes for the concentration of a product to become half of its initial concentration

Correct answer

C. The time it takes for the concentration of a reactant to become half of its initial concentration

Step-by-step solution

The half-life of a reaction as the time in which the concentration of a reactant is reduced to one-half of its initial concentration.
