The answer is a , as aluminium has 13 protons and electrons .
Answer:
The value for the equilibrium constant for the reaction
at 298K .
What would be the value for the equilibrium constant for the following reaction at the same temperature?
![2SO3(g) 2SO2(g)+O2(g)](https://tex.z-dn.net/?f=2SO3%28g%29%20%3C%3D%3E%202SO2%28g%29%2BO2%28g%29)
Explanation:
The Kc value for the reverse reaction of the first reaction that is:
![2SO2(g)+O2(g) 2SO3(g) Kc=4.0*10^{24}\\](https://tex.z-dn.net/?f=2SO2%28g%29%2BO2%28g%29%20%3C%3D%3E%202SO3%28g%29%20%20%20%20%20Kc%3D4.0%2A10%5E%7B24%7D%5C%5C)
![Kc=\frac{SO3^{2} }{SO2^{2}.O2 }](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7BSO3%5E%7B2%7D%20%7D%7BSO2%5E%7B2%7D.O2%20%7D)
For the reverse reaction,
![2SO3(g) 2SO2(g)+O2(g)](https://tex.z-dn.net/?f=2SO3%28g%29%20%3C%3D%3E%202SO2%28g%29%2BO2%28g%29)
![Kc=\frac{SO2^{2}O2 }{SO3^{2}. }](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7BSO2%5E%7B2%7DO2%20%7D%7BSO3%5E%7B2%7D.%20%7D)
So, it is the inverse of the first Kc value.
Hence, the new Kc value is:
![Kc=\frac{1}{4.0*10^{24} } \\ =2.5*10^{-25}](https://tex.z-dn.net/?f=Kc%3D%5Cfrac%7B1%7D%7B4.0%2A10%5E%7B24%7D%20%7D%20%5C%5C%20%20%20%20%3D2.5%2A10%5E%7B-25%7D)
Answer is :
Kc=2.5*10^-25.
Answer:
Sunlight penetrates the top layers of the ocean, so photosynthesis occurs there.
