To determine the effect of heat on the equilibrium position of a reaction, we need to consider the reaction's enthalpy change (ΔH). If the reaction is exothermic (ΔH < 0), it releases heat to the surroundings. On the other hand, if the reaction is endothermic (ΔH > 0), it absorbs heat from the surroundings.
Unfortunately, without knowing the exact wording or additional information, it is difficult to answer the question about the reaction rate shifting to the left or right to restore equilibrium. Typically, changes in temperature affect the rate of a reaction but not the position of the equilibrium. It is the changes in concentration, pressure, or temperature, according to Le Chatelier's principle, that cause the equilibrium position to shift.
