The following concentrations were obtained for the formation of {NH}_{3}({ g}) from {N}_{2}({g}) and {H}_{2}({g}) at equilibrium and at 500 {K}:[{N}_{2}] =1 \times10^{-2}{M}, [{H}_{2}] = 2 \times10^{-2} {M} and [{NH}_{3}]=2 \\times 10^{-2} {M} . The equilibrium constant, K_{c}, for the reaction {N}_{2}({g})+3 {H}_{2}({g}) \⇌2 {NH}_{3}({g}) at 500 {K} is

Correct Answer is : 5×103 mol−2 dm6

5 \\times10^{3} { mol}^{-2} {dm}^{6}

1 \\times10^{3} { mol}^{-2} {dm}^{6}

5 \\times10^{2} { mol}^{-2} {dm}^{6}

2 \\times10^{3} { mol}^{-2} {dm}^{6}
