In the Contact process Give a reason why - vanadium pentoxide is preferred to platinum during the catalytic oxidation of sulphur dioxide.

In the Contact process State why the above catalytic oxidation reaction supplies energy .

State the condition/s required for the following conversion reactions to take place Sulphur dioxide to sulphur trioxide in contact process.

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

In the manufacture of sulphuric acid by contact process give the equation for the conversion of sulphur trioxide to sulphuric acid.

In the the manufacture of sulphuric acid by the Contact process ,give the equations for the conversion of sulphur trioxide to sulphuric acid .

In the Contact process State how would eonvert a ] sulphur b [ iron pyrites to sulphur dioxide in the first step of the Contact process

In the Contact process state why sulphur trioxide vapours are absorbed in concentrated sulphuric acid and not in water to obtain sulphuric acid .

Write balanced chemical equations to show how SO_3 is converted to Sulphuric acid in the contact process.

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. Write the equation for the conversion of sulphur dioxide to sulphur trioxide. Why does this reaction supply energy?
