If an equilibrium reaction has ∆H < O, the reaction will proceed favorably in the forward reaction at?
Answer Details
If an equilibrium reaction has a negative value for enthalpy change (∆H < 0), it means that the forward reaction is exothermic and releases heat. According to Le Chatelier's principle, when heat is added to a system at equilibrium, the equilibrium shifts in the direction that absorbs heat. Thus, when the forward reaction is exothermic, it will proceed favorably in the forward direction at low temperatures since the system will shift in the direction that absorbs heat, which in this case is the forward direction. Therefore, the correct option is "low temperatures."
