Answer» Solution :The important step in manufacture of sulphuric acid is CATALYTIC OXIDATION of `SO_2` to `SO_(3)` `2SO_(2)(g) + O_(2)(g) overset(V_(2)O_(5))to 2SO_(3)(g), DeltaH = -196.6 kJ//"mol"^(-1))` The reaction is exothermic and REVERSIBLE. Hence, low temperature and high pressure shifts the reaction toward product (`SO_(3)`) in accordance to Le-Chatelier.s principle. The process is carried out at 2 bar pressure and 720 K temperature. |
