N2(g) + O2(g) ↔ 2NO(g); ΔH = + 180.6 kJ mol-1 In the reaction above, increase in temperature will

In the given chemical reaction, the enthalpy change is positive (+180.6 kJ/mol) indicating that the reaction is endothermic, meaning it absorbs heat from the surroundings. According to Le Chatelier's principle, an increase in temperature will favor an endothermic reaction. Therefore, an increase in temperature will increase the yield of NO, which is the product of the reaction. Hence, the correct answer is: "increase in the yield of NO."
