The catalyst used in the contact process for the manufacture of tetraoxosulphate (VI) acid is
Answer Details
The catalyst used in the contact process for the manufacture of tetraoxosulphate (VI) acid is "vanadium (V) oxide." The contact process is the industrial method for the production of sulfuric acid. In this process, sulfur dioxide is converted to sulfur trioxide, which is then used to produce sulfuric acid. Vanadium (V) oxide acts as a catalyst in the conversion of sulfur dioxide to sulfur trioxide. It speeds up the reaction rate by providing an alternate pathway for the reaction that has a lower activation energy.
