Question

1. Complete the following table using the words “decrease,” “same,” or “increase” to indicate how the equilibrium concentrations are affected by the stated stress. “Increase” means that when equilibrium is restored, the chemical’s concentration is greater than it was before the stress.

2 NH3(g) ⇌ N2(g) + 3 H2(g)

 

   

Add NH3

Remove some H2

Add N2

Equilibrium Concentration

N2

     

H2

     

NH3

     

 

2.

HP    ⇌     H+ + P-

                                   red              yellow

The above equilibrium system appears orange due to equal concentrations of HP and P-.

    1. (a) What action will shift the equilibrium so the solution turns red?
    2. (b) What could be done to shift the equilibrium so the solution turns yellow?
