Answer

Explanation:

Step1: Recall Le - Chatelier's principle

According to Le - Chatelier's principle, when a system at equilibrium is disturbed, it will shift to counteract the change.

Step2: Analyze the addition of $NO_2$

The reaction is $2NO(g)+O_2(g)\rightleftharpoons 2NO_2(g)+113.06\ kJ$. Adding $NO_2$ (a product) increases its concentration.

Step3: Determine the shift direction

To counteract the increase in $NO_2$ concentration, the reaction will shift to the left (towards the reactants).

Answer:

The reaction shifts left or to reactants.
