why does a reaction shift in endothermic dir when temperature is increased? as we r already giving it heat it should move in a dir where it releases heat, i.e exothermic

Increase in temperature favors endothermic reaction i.e. it will allow the system to absorb more energy because the equilibrium shifts towards the direction in which heat is absorbed to relieve the system of the stress of added heat i.e. to undo the effect of added heat and thus value of K(equilibrium constant) will also increase.
While decrease in temperature favors the exothermic reaction (reverse reaction, i.e., right to left) i.e. K decreases when heat is removed (cooling the system).
