Discuss the theory involved in the manufacture of sulphuric acid by contact process.
The manufacture of sulphuric acid by contact process:
(1) Sulphur is heated in presence of oxygen to form sulphur dioxide.
$$\displaystyle S+O_2 \xrightarrow {\Delta} SO_2$$
(2) Catalytic oxidation of sulphur dioxide gives sulphur trioxide .
$$\displaystyle 2SO_2+O_2 \xrightarrow [\text {450 deg C, 1.5 to 7 atm}]{V_2O_5 \text { Pt asbastos}} SO_3$$
(3) Sulphur trioxide gas is dissolved in sulphuric acid to form oleum.
$$\displaystyle SO_3+H_2SO_4 \rightarrow H_2S_2O_7$$
(4) Oleum is diluted with water to form sulphuric acid.
$$\displaystyle H_2S_2O_7+H_2O \rightarrow 2H_2SO_4$$
