Equilibrium Constant depends on the Temperature.

Hydrogen, H is the element which has no neutron.

Let, the reaction: N2 (g) + 3 H2 (g) ↔ 2 NH3 (g) ∆H = – 92 Kj

The reaction is exothermic, so the reaction approaches to backward with increasing temperature. The production NH3 will be decrease.

On the other hand the reaction approaches to forward with decreasing temperature. The production of NH3 will be Increases.

At 4000C and 5000C temperature, the equilibrium constant will be 1.66 x 10-4 and 1.145 x 10-4. So the production of NH3 increases with decreasing temperature. So the equilibrium constant depends on the temperature.
