Formation of `SO_(3)` by `SO_(2)` and `O_(2)` is favoured by `:-`

The formation of SO_(3) from SO_(2) and O_(2) takes place in the following steps : (i) SO_(2)+2NO_(2) to 2SO_(3)+2NO (ii) 2NO +O_(2) to 2NO_(2)

Platinised asbestos helps in the formation of SO_(3) from SO_(2) and O_(2) . But, if even a small amount of As_(2)O_(3) is present the platinised asbestos does not help in the formation of SO_(3), As_(2)O_(3) acts here as a//an .
