Equation for the decomposition of ammonia:

2NH3->N2+3H2

Equilibrium constant for this equation will be:

Kc=[N2] ([H2]^3) / [NH3]^2

As given Concentration of N2=0.800 M

Concentration of H2=0.420 M

Concentration of NH3=0.250 M

So Kc = ([0.420]^3) * (0.8) / ([0.250]^2)

= 0.9483264

so equilibrium constant will be:

0.9483264
