(a)

Interpretation Introduction

Interpretation:

Interpretation:

The initial concentration at given half-lives has to be determined.

Concept introduction:

Half-life: The time required for half of a reactant to be consumed in a reaction is said to be half-life.

• Half-life of a reaction is represented by the symbol as ${\text{t}}_{\text{1/2}}$.
• Half-life is discovered by Ernst Rutherford's in 1907 from the original term half-life period.
• For the second order reaction ${\text{t}}_{\text{1/2}}\text{=}\frac{\text{1}}{{\text{k[A]}}_{\text{0}}}$
