Exothermic reaction, by decreasing the temperature, equilibrium constant:
Correct answer: E. Increases
- A. Same
- B. Sometimes decreases sometimes increases
- C. Reaction moves backward
- D. Decreases
- E. Increases
Explanation
In exothermic reactions Kc is inversely proportional to temperature it mean when temperature will increase Kc will decrease and when temperature increases Kc decreases.

About Thermochemistry and Energetics of Chemical Reactions
Thermochemistry measures energy changes in chemical reactions and distinguishes exothermic from endothermic processes. Work covers systems, surroundings and state functions, internal energy, the first law of thermodynamics, enthalpy and Hess's law, including the sign conventions used when heat enters or leaves a system.
