Question

A certain reaction occurs in two steps as
(i) $2 S O_{2 (g)} + 2 N O_{2 (g)} \to 2 S O_{3 (g)} + 2 N O_{(g)}$
(ii) $2 N O_{(g)} + O_{2 (g)} \to 2 N O_{2 (g)}$
In the reaction,

N O_{2 (g)}

is intermediate

Solution

The correct option is C $N O_{(g)}$ is intermediate
$N O_{(g)}$ is intermediate as it is produced in the first step and consumed in the second step. A catalyst may be consumed in the first step and produced in the second step.
