A certain reaction ocuurs in two steps as
(I) `2SO_(2(g))+2NO_(2(g)) to 2SO_(3(g))+2NO_((g))`
`(ii) 2NO_((g) ) +O_(2) (g) to 2NO_(2(g))`
In the reaction ,______.

A

`SO_(2("g"))`

B

`NO_(2("g"))`

C

`O_(2("g"))`

D

`NO_(("g"))`

Text Solution

Verified by Experts

The correct Answer is:
B
In these two reaction `NO_(2(g))` is recovered as it is `NO_(2)` accelerates the reaction without any chabnge in itself.
