(a)

Interpretation Introduction

Interpretation:

1. (a) (i) The plots for rate versus [A]t and (ii) [A]t versus time have to be sketched.

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 t12
• Half-life is discovered by Ernest Rutherford's in 1907 from the original term half-life period.
• The half-life period is then shortened as half-life in early 1950s.

(b)

Interpretation Introduction

Interpretation:

(b) The half-life for the given reaction has to be derived.

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 t12
• Half-life is discovered by Ernest Rutherford's in 1907 from the original term half-life period.
• The half-life period is then shortened as half-life in early 1950s.

(c)

Interpretation Introduction

Interpretation:

(c) The time in half-lives when the integrated rate law is no longer valid i.e., [A]t=0 has to be calculated.

Concept introduction:
