Choose the type of catalysis in the following reaction:
Correct answer: A. Homogeneous catalysis
- A. Homogeneous catalysis
- B. Heterogeneous catalysis
- C. Biological catalysis
- D. Gas catalysis
Explanation
The given reaction 2SO2(g) + O2(g) -> 2SO3(g) with NO2(g) as a catalyst represents a type of catalysis known as Homogeneous catalysis.In homogeneous catalysis, the catalyst and the reactants exist in the same phase, which means they are in the same state (in this case, gaseous). In the reaction, the NO2(g) acts as a catalyst, facilitating the conversion of SO2 and O2 into SO3. The NO2 molecules participate in the reaction by temporarily forming intermediate species and subsequently being regenerated, without being permanently consumed or changed.

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
