What is the relationship between Kc (the equilibrium constant) of a given reaction at a given temperature and the temperature the reaction takes place at?

In other words, how does Kc change with respect to temperature?

Any answers would be greatly appreciated

A more woolly explanation invovles moving the equilibrium in the direction of endothermic change as the temperature is increased.

N2 + 3H2 <==> 2NH3 ΔH = -92kJ

Hence increasing the temperature decreases the amount of ammonia present at equilibrium.
