Chemical Kinetics Question 100

Question: The following data are for the decomposition of ammonium nitrate in aqueous solution Volume of $ N_2 $ in cc Time (minutes) 6.25 10 9.50 15 11.42 20 13.65 25 35.05 Finally The order of the reaction is [NCERT 1980]

Options:

A) Zero

B) One

C) Two

D) Three

Show Answer

Answer:

Correct Answer: B

Solution:

$ K=\frac{2.303}{t}\log \frac{{V_{\infty }}}{{V_{\infty }}-V_{t}} $ gives constant value of K. With the given date. Hence it is 1st order.
