Question

28g of N2 and 6g of H2 were kept at 400 degree centigrade,the equilibrium mixture contained 27.54g of NH3. Find the value of Kc in mole^-2L^2 .

Answer 1

You don't have a volume and no way to find it. No way to find pressure either. You can find mols N2, mols H2, and mols NH3 formed and calculate mols N2 and mols H2 at equilbrium. But you have no way to convert that to M
