Answer
The reaction is an endothermic reaction.
If the temperature of the system were increased, the shift would occur towards the right (i.e forward reaction).
Step-by-step explanation
Consider the reaction
2NO2(g) + energy = 2NO(g) + O2(g).
The reaction is endothermic because it absorbs or gains energy.
If the temperature of the system were increased, the shift would occur towards the right (i.e forward reaction) because an increase in temperature favors the endothermic reaction. This means increasing the temperature will shift the equilibrium to the right-hand side of the equation.
