Question 5 0/1 point The equilibrium constant for the gas phase reaction N2 (g) + 3H2(g) + 2NH3 (B) is Keq - 4,34 x 10-3 at 300 °C. At equilibrium, Question 5 The equilibrium constant for the gas phase reaction N2 (8) + 3H2 (g) – 2N63 (g) is keq = 4.34 x 10-3 at 300 °C. At equilibrium, products predominate only reactants are present roughly equal amounts of products and reactants are present only products are present reactants predominate
