Chapter 16, Problem 16.76P

(a)

Interpretation Introduction

Interpretation:

The gold catalyst whether act as homogeneous or a heterogeneous catalyst has to be predicted.

Concept Introduction:

Catalyst: A substance or a compound which promotes the rate of a chemical reaction is said to be catalyst.  Catalysts are classified into two types.  They are homogeneous catalysts and heterogeneous catalysts.

Homogeneous catalyst: In a catalytic reaction the phase of the reactant and catalyst must be in same phase.

Heterogeneous catalysts: In a catalytic reaction the phase of the reactant and catalyst were in different phases.

Homogeneous catalysis: In a chemical catalysis reaction solution by a soluble catalyst is said to be homogeneous catalysis.

Heterogeneous catalysis: In a chemical catalysis reaction, the phases of reactant and catalyst are different.

(b)

Interpretation Introduction

Interpretation:

The reaction energy diagrams for the catalyzed and the uncatalyzed reaction has to be sketched.
