When 5.967 x 10-1 mol of NH3 and 5.967 x 10-1 mol of O2 are introduced into a 1.976 L reaction vessel at a certain temperature a chemist finds that at equilibrium the N2 concentration is 1.317 x 10-1 M: 4NH3(g) + 3O2(g) <==> 2N2(g) + 6H2O (g) What is the value of Kc for this reaction ?

Question

When 5.967 x 10-1 mol of NH3 and 5.967 x 10-1 mol of O2 are introduced into a 1.976 L reaction vessel at a certain temperature a chemist finds that at equilibrium the N2 concentration is 1.317 x 10-1 M:

4NH3(g) + 3O2(g) <==> 2N2(g) + 6H2O (g)

What is the value of Kc for this reaction ?
