The forward reaction is exothermic (shown by the negative enthalpy change) which means that heat is a product of the reaction. According to Le Châtelier's Principle, if the temperature is decreased, the system will try to compensate by producing more heat, so it will shift to the right to produce more N2O4, which is a product and produces heat. Therefore, the equilibrium will shift to the left.
