In the manufacture of sulphuric acid industrially, the key step involved is formation of SO_(3). Higher the yield of SO_(3), greater is the yield of sulphuric acid and moreover lesser is the pollution effect. K_(c ) at relatively higher temperatures (400^(@)C) is found out to be very high and their values gradually decrease with increase in temperature. Based on the data given, predict the favourable conditions for the better yield of SO_(3).

1.	In the manufacture of sulphuric acid industrially, the key step involved is formation of SO_(3). Higher the yield of SO_(3), greater is the yield of sulphuric acid and moreover lesser is the pollution effect. K_(c ) at relatively higher temperatures (400^(@)C) is found out to be very high and their values gradually decrease with increase in temperature. Based on the data given, predict the favourable conditions for the better yield of SO_(3).
