An equilibrium mixture of N2, H2 and NH3 at 700K contains 0.036M H2 and 0.015M H2. At this temperature, Kc for the reation N2(g)+3H2(g) <> 2NH3(g) is 0.29. What is the concentration of NH3?

Solutions

Expert Solution

Given the equilibrium concentration of N₂ = 0.036 M

equilibrium concentration of H₂ = 0.015 M

equilibrium concentration of NH₃ = ?

equilibrium constant , K_c = 0.29

N₂(g)+3H₂(g) 2NH₃(g)

equilibrium constant , K_c = [NH₃(g)]² / ( [ N₂(g)][H₂(g)]³

0.29 = [NH₃(g)]² / ( 0.036 x 0.015³ )

[NH₃(g)]² = 2.35x10^-6

[NH₃(g)] = 1.53x10^-3 M

So the concentration of NH3 is 1.53x10^-3 M
