The order of reaction is:

Options

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

Correct answer

B. One

Step-by-step solution

NH4NO2⟶N2+2H2O\mathrm{NH}_{4} \mathrm{NO}_{2} \longrightarrow \mathrm{N}_{2}+2 \mathrm{H}_{2} \mathrm{O} Volume of N2\mathrm{N}_{2} formed in successive five minutes are 2.75cc,2.40cc2.75 \mathrm{cc}, 2.40 \mathrm{cc} and 2.25cc2.25 \mathrm{cc} which is in decreasing order. So rate of reaction is dependent on concentration of NH4NO2\mathrm{NH}_{4} \mathrm{NO}_{2}. As decrease is not very fast so it will be first order reaction.
