When the temperature in the vessel is decreased, does the equilibrium shift to the right, favoring the product, or to the left, favoring the reactants? Justify your answer.

Answer 1

You would have to know if the reaction is taking in energy/heat or producing energy/heat. If it is taking in energy it would be written on the left like a reactant, if it is producing energy it would be on the right with the products. If you decrease temperature you are decreasing heat, so which side would the reaction move to to compensate for that loss?

Answer 2

Totally agree with Taylor F. You need more info to properly answer this question.
