Question

If an endothermic reaction is in equilibrium, what will happen when you increase the temperature?

Answer 1

Endothermic reaction is when the reaction ends up absorbing heat to break bonds more than that to make bonds. Because of this endothermic process, to start the reaction, the reactants need high activation energy and in terms of temperature, a higher one will favor that, the reason why high temperature favours endothermic reactions and low temperatures favour exothermic reactions.
In the case of your question, the right hand side of the equation is endothermic, therefore increasing temperature, favours the exothermic process, which is in the left hand side, making the system shift to this very side. Hope it did help.
