For the reversible reaction, $N_{2(g)} + 3H_{2(g)} \rightleftharpoons 2NH_{3(g)}$. When the partial pressure is measured in atmosphere, the value of $K_p$ at $500^{\circ}\text{C}$ is $1.44 \times 10^{-5}$. The value of $K_c$ when the concentration is expressed in $\text{mol L}^{-1}$ is:

  • A
    $\frac{1.44 \times 10^{-5}}{(0.082 \times 500)^{-2}}$
  • B
    $\frac{1.44 \times 10^{-5}}{(8.314 \times 773)^{-2}}$
  • C
    $\frac{1.44 \times 10^{-5}}{(0.082 \times 773)^{2}}$
  • D
    $\frac{1.44 \times 10^{-5}}{(0.082 \times 773)^{-2}}$
