Answer #1

Kc is defined as concentration of product by concentration of reactant with each concentration term raised to power that is equal to its stoichiometric coefficient in balanced equation

So,

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

2 = 0.5^2 / [N2]*(2.0)^3

[N2] = 0.25 / (2*8.0)

[N2] = 0.016 M

Answer: D
