Answer:
The rate equation for this reaction:
![R=k[NH_3]^0](https://tex.z-dn.net/?f=R%3Dk%5BNH_3%5D%5E0)
Explanation:
Decomposition of ammonia:
Rate law of the can be written as;
![R=k[NH_3]^x](https://tex.z-dn.net/?f=R%3Dk%5BNH_3%5D%5Ex)
1) Rate of the reaction , when ![[NH_3]=2.0\times 10^{-3} M](https://tex.z-dn.net/?f=%5BNH_3%5D%3D2.0%5Ctimes%2010%5E%7B-3%7D%20M)
![1.5\times 10^{-6} M/s=k[2.0\times 10^{-3} M]^x](https://tex.z-dn.net/?f=1.5%5Ctimes%2010%5E%7B-6%7D%20M%2Fs%3Dk%5B2.0%5Ctimes%2010%5E%7B-3%7D%20M%5D%5Ex)

2) Rate of the reaction , when ![[NH_3]=4.0\times 10^{-3} M](https://tex.z-dn.net/?f=%5BNH_3%5D%3D4.0%5Ctimes%2010%5E%7B-3%7D%20M)
![1.5\times 10^{-6} M/s=k[4.0\times 10^{-3} M]^x](https://tex.z-dn.net/?f=1.5%5Ctimes%2010%5E%7B-6%7D%20M%2Fs%3Dk%5B4.0%5Ctimes%2010%5E%7B-3%7D%20M%5D%5Ex)

[1] ÷ [2]
![\frac{1.5\times 10^{-6}M/s}{1.5\times 10^{-6}M/s}=\frac{k[2.0\times 10^{-3}M]^x}{k[4.0\times 10^{-3}M]^x}](https://tex.z-dn.net/?f=%5Cfrac%7B1.5%5Ctimes%2010%5E%7B-6%7DM%2Fs%7D%7B1.5%5Ctimes%2010%5E%7B-6%7DM%2Fs%7D%3D%5Cfrac%7Bk%5B2.0%5Ctimes%2010%5E%7B-3%7DM%5D%5Ex%7D%7Bk%5B4.0%5Ctimes%2010%5E%7B-3%7DM%5D%5Ex%7D)
On solving for x , we get ;
x = 0
The rate equation for this reaction:
Answer:
The shape of a molecule is mostly determined by repulsion among the pairs of electrons around a central atom.
Answer:
