Options

  1. AZero
  2. BOne
  3. CTwo
  4. DThree

Correct answer

B. One

Step-by-step solution

NH ₄ NO ₂ N ₂+2 H ₂ O Volume of N ₂ formed in successive five minutes are 2.75 cc , 2.40 cc and 2.25 cc which is in decreasing order. So rate of reaction is dependent on concentration of NH ₄ NO ₂ . As decrease is not very fast so it will be first order reaction.
