In chamber process of sulphuric acid manufacture in industry, the gas phase oxidation of SO2 to SO3 is accomplished by a ______________ reaction ?
Correct answer: C. Catalytic homogenous
- A. Non-catalytic homogeneous
- B. Non-catalytic heterogeneous
- C. Catalytic homogenous
- D. Catalytic heterogeneous
Explanation
In the chamber process, sulphur dioxide is oxidised in the gas phase with nitrogen oxides acting as catalysts. Since both catalyst and reactants are in the gas phase, the reaction is catalytic homogeneous.
