The activation energy of the un-catalyzed third order oxidation reaction of sulfur
dioxide (SO 2 ) (g) to form sulfur trioxide (SO 3 ) (g) is 300 KJ/mol. but when the reaction is
catalyzed by platinum (Pt) (s) the rate of the oxidation reaction has dramatically
increased and the activation energy is found to be 50 KJ/mol.
(a) Write the balanced chemical equation for the reaction showing the catalyst used.
(b) Name the type of catalyst used.
(c) Name the type of catalysis
(d) Calculate the Catalyst Reactivity Ac at 427 °C. (R=8.314 JK -1 mol. -1 ).
(e) What do you think will happen to the order of the catalyzed reaction compared
with the un-catalyzed one.
---------------
Sketch a Diagrammatic representation for the activation energy change of a
bimolecular reacting system in;
(i) Un-catalyzed Reaction. A + B P
(ii) Negative Catalyzed Reaction. A + B C (Catalyst) P
and Discuss the role of the catalyst in such reactions by showing the mechanism
steps for each reaction.
