Answer:
a. K = [H+][NO2-]/[HNO2]
Explanation:
The computation of the expression of the equilibrium constant is shown below:
Given that the weak acid is HNO_2 that exist in the solution that aqueous
The dissociation equation of 
Now
Acidionization constant i.e.
![k_a = \frac{[NO_{2}^{-}][H^{+}]}{HNO_{2}}](https://tex.z-dn.net/?f=k_a%20%3D%20%5Cfrac%7B%5BNO_%7B2%7D%5E%7B-%7D%5D%5BH%5E%7B%2B%7D%5D%7D%7BHNO_%7B2%7D%7D)
Therefore the correct option is a.
Hence, the same is to be considered
Answer:
2CO₂ ⇄ 2CO + O₂.
Explanation:
- <em>The equilibrium constant (Keq)</em> for a reaction is the ratio of the concentration of the products to the reactants, each one is raised to each molar coefficient.
So, for Keq = [CO]²[O₂]/[CO₂]²,
It is clear that the products are CO and O₂, while the reactant is CO₂.
So, the reaction for this is:
<em>2CO₂ ⇄ 2CO + O₂.</em>
Fusion occurs constantly on our sun, which produces most of its energy via the nuclear fusion of hydrogen into helium. Neither do fusion reactions produce the large amounts of dangerous radioactive waste that fission reactions do. That's why it's such a dreamy source of energy.
