Use the reaction N2(g) + 3H2(g) 2NH3(g) to answer the following questions a. 1 pt: What does Le Châtelier's principle predict would happen to the equilibrium conditions if N2(g) + 3H2(g) were added to the system?

b. 1 pt: What would happen to the equilibrium if the pressure were decreased?

c. 2 pts: Write the equation for calculating Keq

d. 3 pts: Calculate the value for Keq given the following concentrations

[NH3] = 6 M

[H2] = 4 M

[N2] = 3 M

Explanation:

a ) If N₂(g) and 3H₂(g) is added to the system , 2 moles of additional  ammonia will be produced .

b ) If pressure is decreased , less amount of ammonia will be formed, because forward reaction reduces the pressure. So, reaction will take place in reverse direction.

c ) Keq = [ NH₃ ] ² / [ N₂ ] [ H₂]³

d ) Substituting the given values in the equation ,

Keq = [ 6M ] ² / [ 3M] [ 4M]³

= 36 / 3 x 64 M⁻²

= 18.75 x 10⁻² M⁻² .
