Chapter 20, Problem 98SAE

Interpretation Introduction

(a)

Interpretation:

Symbol ${\left[\text{A}\right]}_0$ should be defined.

Concept introduction:

${\left[\text{A}\right]}_0$ is related to the study of the kinetics of the reaction.

Interpretation Introduction

(b)

Interpretation:

Symbol $k$ should be defined.

Concept introduction:

$k$ is used as the proportionality constant in rate law expression of a chemical reaction.

Interpretation Introduction

(c)

Interpretation:

Symbol $t_{1/2}$ should be defined.

Concept introduction:

$t_{1/2}$ is used to shows the decay of radioactive species.

Interpretation Introduction

(d)

Interpretation:

Zero order reaction should be defined.

Concept introduction:

Order of a reaction is defined as the summation of the stoichiometric coefficient of the reactants in the rate law expression. Order for a chemical reaction is determined experimentally and can have a negative value also.

Interpretation Introduction

(e)

Interpretation:

Catalyst should be defined.

Concept introduction:

Catalyst is generally used to carry out the reaction at a faster rate without being consumed in the reaction.
