If at equilibrium state temperature is increased, it will favour:
Correct answer: B. Endothermic Reactions
- A. Exothermic Reactions
- B. Endothermic Reactions
- C. Reversible gaseous reactions
- D. Irreversible reactions
Explanation
Option B is correct since an increase in temperature produces more heat, so to absorb that heat, the side of the equilibrium favoring the endothermic reaction will be preferred.Option A is incorrect since exothermic reactions will serve to increase the heat in an already greater temperature environment which is not feasible.Option C is incorrect since an increase in temperature will favor the shift of the endothermic reaction and not both sides.Option D is incorrect since irreversible reactions have only one side which may be exothermic or endothermic. Irreversible reactions do not achieve an equilibrium state.

About Chemical Equilibrium
Reversible reactions reach dynamic equilibrium when forward and reverse rates become equal, and Le Chatelier's principle predicts the effect of changing concentration, pressure or temperature. The chapter also covers solubility product, the common ion effect, buffer action and the conditions used in Haber's process, with equilibrium shifts distinguished from changes in the equilibrium constant.
