Hello!
<span>The position of the equilibrium for a system where k = 4.6 × 10-15 can be described as being favored to
the left; the concentration of products is relatively
small.
For a reaction where A produces B, the chemical equation is the following:
A </span>⇄ B
The equilibrium constant expression is the following:
![k= \frac{[B]}{[A]}](https://tex.z-dn.net/?f=k%3D%20%5Cfrac%7B%5BB%5D%7D%7B%5BA%5D%7D%20)
From this equation, we can see that when the constant is
small, as in the case of the exercise, the concentration of products is also small, and the equilibrium is favored to the left.
Have a nice day!
Answer:
The octet rule means that atoms need a total of 8 valence electrons to fill their valence shell. Hydrogen only needs two to fill its valence shell.
Explanation:
All atoms except for hydrogen can hold a total of 8 valence electrons in their outer energy levels (2 in the s level, 6 in the p level). Hydrogen only has two electrons total, so it does not require more than the s level and two electrons to have a full valence.
