Question:

A reactant decomposes with a half-life of 12.7 s when its initial concentration is 0.319 M.

When the initial concentration is 1.34 M, this same reactant decomposes with a half-life of 53.5 s.

A reactant decomposes with a half-life of 12.7 s when its initial concentration is 0.319 M.

When the initial concentration is 1.34 M, this same reactant decomposes with a half-life of 53.5 s.

1. What is the order of the reaction?

  • a. 0
  • b. 1
  • c. 2

b. What is the value and unit of the rate constant for this reaction?

Half-life and Quater life

When 75 % of the initial concentration of the reactants has been converted into the product. Or we can say that 25% of the initial concentration is left on the reactants side. This time period is known as Quarter life.

In the case of half-life, 50% of the concentration of the reactants is consumed and 50% remains.

Answer and Explanation:

a. Calculation of order of the reaction

The relation between half-life and the initial concentration of the reactants is written below:

{eq}t_{\fra...
