Answer:
b- 4.4 * 10^-12.
Explanation:
Hello.
In this case, as the reaction:
A + 2B → 3C
Has an equilibrium expression of:
![K_1=\frac{[C]^3}{[A][B]^2}=2.1x10^{-6}](https://tex.z-dn.net/?f=K_1%3D%5Cfrac%7B%5BC%5D%5E3%7D%7B%5BA%5D%5BB%5D%5E2%7D%3D2.1x10%5E%7B-6%7D)
If we analyze the reaction:
2A + 4B → 6C
Which is twice the initial one, the equilibrium expression is:
![K_2=\frac{[C]^6}{[A]^2[B]^4}](https://tex.z-dn.net/?f=K_2%3D%5Cfrac%7B%5BC%5D%5E6%7D%7B%5BA%5D%5E2%5BB%5D%5E4%7D)
It means that the equilibrium constant of the second reaction is equal to the equilibrium constant of the first reaction powered to second power:
Thus, the equilibrium constant of the second reaction turns out:
Therefore, the answer is b- 4.4 * 10^-12.
Best regards.
Is there something else that goes along with the question?
Answer:
red supergiants is the answer
Answer
Africa
Explanation:
Burning fossil fuels and deforestation is disturbingly heightened in Africa with almost no viable measure taking to control it's effect. No effective programs are presently in place to control excessive tree falling used for herbs, firewood, charcoal business and a whole lot. Below standard carbon rating PMS are in high circulation with fumes, carbon monoxide is full abundance in the atmosphere. Presently, all these unchecked activities have resulted into unexplainable excessive increase in temperatures, breeding neck twisting diseases, severe skin infections, dehydration and increase diabetes. Drought has eaten up landlocked cities in Nigeria and Central Africa. Infact farmers have lost count of the usual natural cycle of rainfall and the beginning of each farming season due to this essential evil of climate change

134 kilo joule = 134 x 0.239006
= 32.026804 calories
