A reaction vessel contains NH3, N2, and H2 at equilibrium at acertain temperatur

Question

A reaction vessel contains NH3, N2, and H2 at equilibrium at acertain temperature. The equilibrium concentrations are [N2]= 0.11M, [H2]=1.46M, and [NH3]=0.70M. Calculate the equilibrium constant,Kc1 if the reaction is represented as: (1/2) N2(g) + (3/2) H2 (g) -->NH3(g)                                          <-- A reaction vessel contains NH3, N2, and H2 at equilibrium at acertain temperature.

Explanation / Answer

For thereaction         (1/2) N2(g) + (3/2) H2 (g) -->NH3(g)                          Equillibrium constant, Kc = [NH3] /[N2]1/2[H2]3/2 By putting the equillibrium concentrations in thisreaction weget                                                  Kc = 0.70 / (0.11)1/2 (1.46)3/2                                                        =0.70 / (0.331)(1.76)                                                       = 1.20                                                        =0.70 / (0.331)(1.76)                                                       = 1.20
