Answer:

Shifts right

Step-by-step explanation:

A positive ΔH means that the reaction is endothermic. When the temperature is increased, the reaction will shift to the right.

You can think about it this way:

In an endothermic reaction, the heat is on the reactant side of the reaction. In an exothermic reaction, the heat is on the product side of the reaction. When the temperature is increased, the reaction will shift to the opposite side of the reaction where the heat is. So say the heat is on the reactant side, then the reaction will shift to the products when the temperature is increased.
