Answer: Option (b) is the correct answer.
Explanation:
Chemical properties are defined as the properties which tend to chemical composition of a substance. Neutral elements with similar number of valence electrons tend to show similar chemical properties as these have same reactivity which actually affects their chemical properties.
This means that elements of the same group tend to show similar chemical properties.
For example, oxygen and sulfur atom are both group 16 elements and they have 6 valence electrons. Therefore, they show similar chemical properties.
Thus, we can conclude that a pair of O and S elements is expected to be most similar in their chemical properties.

<u>Answer:</u> The equilibrium constant for the reaction is 54.47
<u>Explanation:</u>
The equilibrium constant is defined as the ratio of the concentration of products to the concentration of reactants raised to the power of the stoichiometric coefficient of each. It is represented by the term 
The given chemical equation follows:
The expression for equilibrium constant will be:
![K_{eq}=\frac{[HI]^2}{[H_2][I_2]}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BHI%5D%5E2%7D%7B%5BH_2%5D%5BI_2%5D%7D)
We are given:
![[HI]_{eq}=1.3544\times 10^{-2}M](https://tex.z-dn.net/?f=%5BHI%5D_%7Beq%7D%3D1.3544%5Ctimes%2010%5E%7B-2%7DM)
![[H_2]_{eq}=4.5647\times 10^{-3}M](https://tex.z-dn.net/?f=%5BH_2%5D_%7Beq%7D%3D4.5647%5Ctimes%2010%5E%7B-3%7DM)
![[I_2]_{eq}=7.378\times 10^{-4}M](https://tex.z-dn.net/?f=%5BI_2%5D_%7Beq%7D%3D7.378%5Ctimes%2010%5E%7B-4%7DM)
Putting values in above expression, we get:
Hence, the equilibrium constant for the reaction is 54.47
