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.

• A. Zero
• B. One
• C. Two
• D. Three

Answer 1

Answer: (B)

One

Answer 2

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