Answer: An exothermic reaction's equilibrium shifts to the left when pressure is increased and shifts to the right when temperature is increased.
Explanation: In exothermic reactions, the side comprising fewer gas moles is deemed to be positively impacted by enhanced pressure, resulting in a shift towards the reactants. Elevated temperatures provide a preferential environment for endothermic reactions which are characterized by the absorption of thermal energy. When an exothermic reaction occurs, the application of heat results in a shift of the equilibrium towards the endothermic side, as a means of absorbing the excess thermal energy.
