Chapter 25.4, Problem 25.5CYU

a)

Interpretation Introduction

Interpretation: According to rate law that is the concentrations or pressure of the reactants and products of constant parameters is called rate law.

Concept introduction:

Half-life: The time required for a sample to decay half of the initial quantity. It is considered as first-order chemical reaction and is independent of the amount of sample.

b)

Interpretation Introduction

Interpretation:

The time required for a sample of tritium to decay to one eighth of its activity has to be calculated.

Concept introduction:

Half-life: The time required for a sample to decay half of the initial quantity. It is considered as first-order chemical reaction and is independent of the amount of sample.

According to rate law that is the concentrations or pressure of the reactants and products of constant parameters is called rate law.

c)

Interpretation Introduction

Interpretation:

The length of time necessary for the sample to decay to 1% of its original activity has to be estimated.

Concept introduction:

Half-life: The time required for a sample to decay half of the initial quantity. It is considered as first-order chemical reaction and is independent of the amount of sample.
