A certain reaction occurs in two steps as: (i) 2 S O 2 g + 2 N O 2 g → 2 S O 3 g + 2 N O g (ii) 2 N O g + O 2 g → 2 N O 2 g In the reaction,

Options

  1. AN O 2 g is intermediate
  2. BN O g is intermediate
  3. CN O g is catalyst
  4. DO 2 g is intermediate

Correct answer

B. N O g is intermediate

Step-by-step solution

On adding equation (1) & (2) we get 2 S O 2 + 2 N O 2 + O 2 → 2 S O 3 + 2 N O 2 The N O is not considered. It is a intermediate in the reaction.
