Should shift to the right, endothermic reaction because of the +187 kJ. Per Le Chatelier's Principle, an increase in the temperature of the system causes equilibrium to shift away from the heat to balance out the reaction.

The trick is figuring out if the reaction is endothermic or exothermic. If you have a + kj value, then your reaction should be endothermic, and the energy is on the reactant side because it is being absorbed. If you have a - kj value, then your reaction is exothermic.

This question was marked wrong. :(

Is this not a shift to the right? Because it is endothermic?
