${\mathrm{K}}_{\mathrm{W}}$of ${\mathrm{H}}_2\mathrm{O}$ at $373 \mathrm{K}$ is $1\times {10}^{-12}$, Identify which of the following is incorrect.

For a reaction ${\mathrm{N}}_2+3{\mathrm{H}}_2\rightleftharpoons 2{\mathrm{NH}}_3$, the value of ${\mathrm{K}}_{\mathrm{C}}$ does not depends upon:

(a) Initial concentration of the reactants

(b) Pressure

(c) Temperature

(d) Presence of catalyst

 For ${\mathrm{N}}_{\mathrm{2}}+3{\mathrm{H}}_{\mathrm{2}}\rightleftharpoons 2{\mathrm{NH}}_{\mathrm{3}}$ equilibrium constant is $\mathrm{K}$, then equilibrium constant for $2{\mathrm{N}}_{\mathrm{2}}+6{\mathrm{H}}_{\mathrm{2}}\rightleftharpoons 4{\mathrm{NH}}_{\mathrm{3}}$is:
