A student ran the following reaction in the laboratory at 651 K:
2 NH3(g) N2(g) + 3 H2(g)
When she introduced 8.75E-2 moles of NH3(g) into a 1.00 Liter container, she found the equilibrium concentration of H2(g) to be 0.119 M.
Calculate the equilibrium constant, Kc, she obtained for this reaction.
See your other post above. Same problem. Different numbers.
