Increasing temperature is like adding heat. According to LeChatlier's principle, adding something to one side of an equilibrium causes it to shift and consume some of what you added. Therefore, increasing temperature favors the endothermic direction of the reaction. If however, there is a sizable entropy change for the equilibrium, increasing temperature will favor the direction increasing entropy. This is because the equilibrium is determined by Gibb's free energy, the difference between the change in enthalpy and the change in entropy times the temperature. As temperature increases, the entropy term becomes more important.
