Question

For the gas phase decomposition of nitrogen dioxide at 383 °C
2 NO₂2 NO + O₂
the following data have been obtained:

[NO₂], M	0.230	9.72×10^-2	6.16×10^-2	4.23×10^-2
time, s	0	11.0	22.0	33.0

The average rate of disappearance of NO₂ over the time period from t = 11.0 s to t = 22.0 s is _____ M s^-1.

Expert Solution

Step 1

Given:

$2 {NO}_{2} \to 2 NO + O_{2}$

For any reaction:

$aA + bB \to cC + dD$

The rate of the reaction is given by:

$rate = - \frac{1}{a} \frac{∆ [A]}{∆ t} = - \frac{1}{b} \frac{∆ [B]}{∆ t} = \frac{1}{c} \frac{∆ [C]}{∆ t} = \frac{1}{d} \frac{∆ [D]}{∆ t}$

Here negative sign denotes the disappearance of the reactants.
