Write the catalyst and equations of ostwald's process.

Explanation

Platinised asbestors is used as catalyst in ostwald.s process at 573 K. The chemical equation in the process are: `2SO_2(g) + O_(2)(g) to 2SO_(3)(g)`
`SO_(3)(g) + H_(2)SO_(4)(aq) to underset("oleum")H_2S_2O_7(l)`
`H_2S_2O_(7)(l) + H_2O(l) to 2H_2SO_(4)(aq)`.
