This will decrease the concentration of NO.

Work Step by Step

Because the reaction is exothermic (as shown by the negative enthalpy value) heat acts as a product. Thus, when the reaction shifts to the left, the temperature decreases. Furthermore, in response to the increase in temperature, the reaction will shift left to compensate, decreasing the concentration of NO.
