(b) 2 N2(g) + 4 H2O(g)4 NO(g) + 4 H2(g)

At a particular temperature, the equilibrium constants for the following reaction is:

2NO(g) + 2H₂(g) ⇄ N₂(g) + 2H₂O(g)   Kc = 6.7x10²      

So, the equilibrium constants for the given reactions are:

a. NO(g) + H₂(g) ⇄ 1/2N₂(g) + H₂O(g)   Kc = 2.6x10

b. 2N₂(g) + 4H₂O(g) ⇄ 4NO(g) + 4H₂(g)    Kc = 2.2x10⁻⁶  

The first reaction is:

2NO(g) + 2H₂(g) ⇄ N₂(g) + 2H₂O(g)   (1)

The equilibrium constant of the above reaction is:

   (2)  

Now, let's find the equilibrium constant for the given reactions.

a) The reaction is:

NO(g) + H₂(g) ⇄ 1/2N₂(g) + H₂O(g)   (3)

So, the constant for the reaction (3) is:

  (4)

When comparing equations (2) and (4), we can see that:

So, the equilibrium constant of the reaction (3) is:

Hence, the equilibrium constant for reaction (3) is 2.6x10.

b) The given reaction is:

2N₂(g) + 4H₂O(g) ⇄ 4NO(g) + 4H₂(g)    (5)

And the equilibrium constant is:

  (6)

From equations (2) and (6), we have first:

and second:

Hence, the equilibrium constant of the reaction (5) is:

Therefore, the equilibrium constant for this reaction is 2.2x10⁻⁶.

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
