Relationship between Kc and temperature.
Afternoon Chemists.
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.

Does that imply that Kc is directly proportional to temperature for reactions where the forward reaction is exothermic and inversely proportional when the forward reaction is endothermic?
