pav-90 [236]

Answer:

Average rate of reaction is 0.000565 M/min

Explanation:

Applying law of mass action for the given reaction:

Average rate = $-\frac{1}{2}\frac{[N_{2}O_{5}]}{\Delta t}=\frac{1}{4}\frac{\Delta [NO_{2}]}{\Delta t}=\frac{\Delta [O_{2}]}{\Delta t}$

Where, $-\frac{1}{2}\frac{[N_{2}O_{5}]}{\Delta t}$ represents average rate of disappearance of $N_{2}O_{5}$ , $\frac{1}{4}\frac{[NO_{2}]}{\Delta t}$ represents average rate of appearance of $NO_{2}$ and $\frac{[O_{2}]}{\Delta t}$ represents average rate of appearance of $O_{2}$
