Discuss the structures of sulphur dioxide and sulphur trioxide molecules.

Sulphur dioxide affects

State the conditions required for the following reaction to take place : Any two conditions for the conversion of sulphur dioxide to sulphur trioxide.

Some bacteria obtain their energy by oxidising sulphur, producing sulphuric acid as a by-product. In the laboratory, or in industry, the first step in the conversion of sulphur to sulphuric acid is to produce sulphur dioxide. The sulphur dioxide is converted to sulphur trioxide, which reacts with water to give sulphuric acid. Name one catalyst used industrially which speeds up the conversion of sulphur dioxide to sulphur trioxide.

Name the catalyst which helps in the conversion of sulphur dioxide to sulphur trioxide in step C.

(i) The flow chart below shows steps in the Contact process or the manufacture of sulphuric acid : (ii) Write equations for : (1) The roasting of iron pyrites. (2) Formation of sulphur trioxide from sulphur dioxide.(III) (3) Platinum was the catalyst used in the conversion of sulphur dioxide to sulphur trioxide. What is the common name of the catalyst used nowadays ? (4) Give the formula of oleum. (5) Name the substance which is added to change oleum into sulphuric acid.
