effect of temperature on equilibrium?

[OU11BB]

I know that temperature can effect the position of the equilibrium, but i was wondering how it effects the numerical value of the equilibrium constant? Can somebody give me an example? Thanks for your time.

I think it will depend on which type of reaction we r talking about (endothermic or exothermic) If it is endothermic, increasing temperature will shift the reaction to the right. (Keq increases) If it is exothermic, increasing temperature will shift the reaction to the left. (Keq decreases)
