How does temperature affect dynamic equilibrium?
Increase in temperature, will favor the endothermic reaction.
Decrease in temperature, will favor the exothermic reaction.
You can remember this very easily.
A)If you increase T , the system will counteract this change by absorbing the heat. Therefore, it favors endothermic reactions.
System at equilibrium is at 200 degree celsius and the temperature is raised to 400C. The system will cool itself down by absorbing the excess heat. - Endothermic
B)If you decrease T , the system will counteract this change by releasing heat. Therefore, it favors exothermic reactions.
System at equilibrium is at 500C and the temperature is decreased to 300C. The system will react by releasing heat to adapt to this change. - Exothermic
