Answer : The correct option is, (D) 
Explanation : Given,
Concentration of 
= 3 M
Concentration of 
= 1 M
Concentration of 
= 2 M
The given balanced equilibrium reaction is,
The expression for equilibrium constant for this reaction will be,
![K_{eq}=\frac{[NH_3]^2}{[N_2][H_2]^3}](https://tex.z-dn.net/?f=K_%7Beq%7D%3D%5Cfrac%7B%5BNH_3%5D%5E2%7D%7B%5BN_2%5D%5BH_2%5D%5E3%7D)
Now put all the given values in this expression, we get the value of 
Therefore, the value of for the given reaction is, 1.125
D but I’m not to sure about it
Answer:
Energy of motion is called
Answer: It is the number in the upper left (atomic number).
Explanation: The atomic number is normally the number of protons. I hope this helps.
An analogy is the closest way to compare something to another that may not be related so that would be my pick. If that’s not it I guess he could maybe be making an observational opinion about it? Good luck hope this helped. Analogy
