The shift in equilibrium is in the reverse direction, resulting in less product.


The reaction as written

#H_2(g)+I_2(g) rightleftharpoons 2HI(g)#

is exothermic (heat is produced).

When you raise the temperature, you are adding more heat to the system.

According to Le Chatelier's principle, the system will shift in a manner that counteracts these additional heat. This is accomplished by shifting equilibrium in the endothermic direction, as this will cause energy to be absorbed.

The endothermic direction in this case is in the reverse direction, so the shift in equilibrium will result in less product and more reactant.
