Question

An equilibrium mixture of N2, H2, and NH3 at 700 K contains 0.031 M N2 and 0.52 M H2. At this temperature, Kc for the reaction is 0.29. What is the concentration of NH3?

N2(g) + 3H2(g) (equilibrium arrow) 2NH3(g)

Answer 1

Set up K expression, substitute the equilibrium mixture of N2 and H2 and solve for NH3.
