Answer: a) ![1.7\times 10^{-4}](https://tex.z-dn.net/?f=1.7%5Ctimes%2010%5E%7B-4%7D)
b) ![3.4\times 10^{-4}](https://tex.z-dn.net/?f=3.4%5Ctimes%2010%5E%7B-4%7D)
Explanation:
The reaction is :
![2N_2O_5(g)\rightarrow 4NO_2(g)+O_2(g)](https://tex.z-dn.net/?f=2N_2O_5%28g%29%5Crightarrow%204NO_2%28g%29%2BO_2%28g%29)
Rate = Rate of disappearance of
= Rate of appearance of
Rate =
= ![\frac{d[NO_2]}{4dt}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BNO_2%5D%7D%7B4dt%7D)
Rate of disappearance of
=
= ![\frac{0.100-0.066}{200-0}=1.7\times 10^{-4}](https://tex.z-dn.net/?f=%5Cfrac%7B0.100-0.066%7D%7B200-0%7D%3D1.7%5Ctimes%2010%5E%7B-4%7D)
a) Rate of disappearance of
= ![-\frac{d[N_2O_5]}{2dt}](https://tex.z-dn.net/?f=-%5Cfrac%7Bd%5BN_2O_5%5D%7D%7B2dt%7D)
Rate of appearance of
= ![\frac{d[NO_2]}{4dt}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BNO_2%5D%7D%7B4dt%7D)
b) Rate of appearance of
= ![\frac{d[NO_2]}{dt}=2\times 1.7\times 10^{-4}}=3.4\times 10^{-4}](https://tex.z-dn.net/?f=%5Cfrac%7Bd%5BNO_2%5D%7D%7Bdt%7D%3D2%5Ctimes%201.7%5Ctimes%2010%5E%7B-4%7D%7D%3D3.4%5Ctimes%2010%5E%7B-4%7D)
