The standard equilibrium constant, Kp at 298 K for the reaction, $$N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3 (g) is 5.8 \times 10^5$$. The value of standard equilibrium constant, if the concentration of gases is expressed in terms of mol/L, will be :
[Given : R = 0.08314 L bar $$K^{-1} mol^{-1}$$]

A

$$3.99 \times 10^9$$

B

$$3.51 \times 10^6$$

C

$$3.84 \times 10^7$$

D

$$3.56 \times 10^8$$
