In endothermic reactions heat is absorbed,then why there is rise in temperature?
Asked by devangi meena | 06 Jun, 2013, 09:04: PM
answered-by-expert Expert Answer
Endothermic reaction is a process in which a system absorbs heat from its surroundings. Since endothermic reactions absorb heat, this means that heat is added to the system.
 
According to Le Chatelier's principle, for an endothermic reaction; increase in temperature shifts the equilibrium in the direction of endothermic reaction. This is because the equilibrium shifts towards the direction in which heat is absorbed in order to relieve the system of the stress of added heat due to increase in temperature.
