(a)
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
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:
The reaction energy diagrams for the catalyzed and the uncatalyzed reaction has to be sketched.
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.
