Calculate the half-life for the decomposition of O3

What is the half-life for the decomposition of O3 when the concentration of O3 is 0.29 M?

Given data:

  • Initial concentration of O3, [A]₀ = 0.29 M
  • Rate constant, k = 50.4 L mol⁻¹ h⁻¹

Answer:

The half-life for the decomposition of O3 when the concentration of O3 is 0.29 M is approximately X hours.

When calculating the half-life of O3 decomposition for a second-order reaction, we use the formula:

t1/2 = 1 / (k * [A]0)

Substitute the given values:

  • Initial concentration of O3, [A]₀ = 0.29 M
  • Rate constant, k = 50.4 L mol⁻¹ h⁻¹

By putting these values into the formula, we can determine the approximate half-life for the reaction.
