Equilibrium constant ${\mathrm{K}}_{\mathrm{C}}$ for the following reaction at 800 K is, 4
$\mathrm{N}{\mathrm{H}}_3\left(\mathrm{g}\right)\rightleftharpoons \frac{1}{2}{\mathrm{N}}_2\left(\mathrm{g}\right)+\frac{3}{2}{\mathrm{H}}_2\left(\mathrm{g}\right)$
The value of ${\mathrm{K}}_{\mathrm{P}}$ for the following reaction will be
${\mathrm{N}}_2\left(\mathrm{g}\right)+3{\mathrm{H}}_2\left(\mathrm{g}\right)\rightleftharpoons 2\mathrm{N}{\mathrm{H}}_3\left(\mathrm{g}\right)$

• A

  ${\left(\frac{800\mathrm{R}}{4}\right)}^{2-}$
• B

  $16\times (800\mathrm{R}{)}^2$
• Correct answer
  C

  ${\left[\frac{1}{4\times 800\mathrm{R}}\right]}^2$
• D

  ${\left(800\mathrm{R}\right)}^{1/2}4$

Hence, the correct answer is option: 'C'.
