Answer:
Question 1: Conversion of SO3 into concentrated sulphuric acid.
Question 2: It is necessary to provide heat to the reaction mixture.
Explanation:
Question 1: The first thing you do is dissolve the sulfur trioxide in concentrated sulphuric acid, which produces disulfuric acid. It cannot be carried out by a simple reaction of sulfur trioxide with water. Disulfuric acid does react with water safely, breaking down into 97-99% concentrated sulfuric acid.
Question 2: One reason is due to kinetics (low temperatures will cause the equilibrium to be displaced, but the reaction will be slower) and the other is due to the performance of the catalyst. Thus, the temperature used must be high, since the catalyst works well in this way, and produces a sufficiently high proportion of SO3 in the equilibrium mixture and at a sufficiently high speed.
