In the preparation of H2SO4 the catalyst and the inhibitor, respectively ,are​

Answer 1

hey mate

 

he steps involved in the manufacture of sulphuric acid by contact process are as shown:

(1) Sulphur (or iron pyrites) are burnt in air to form sulphur dioxide.

 S+O2→SO4

FeS2+11O2  →2Fe2O3  +8SO2

 

 

(2) Catalytic oxidation of sulphur dioxide to sulphur trioxide.

 2SO2+O2(catalystV2O5)2SO3ΔrHo  =−196.6kJ

The reaction is reversible and exothermic.

(3) Sulphur trioxide is dissolved in 98% sulphuric acid to form oleum (fuming sulphuric acid).  

 SO3+H2SO4→H2S2O7

(4) Oleum is diluted with water to form sulphuric acid of desired concentration.

   H2S2O7+H2O→2H2SO4
