Why does an increase in temperature increase the rate of exothermic as well as endothermic reactions?

Answer 1

You may be confused kinetic chemical reaction study with thermodynamic chemical reaction study. Please understand that kinetic chemical reaction studies the rate of the reaction, but does not worry about whether the reactants or the products are favored or not. A fast reaction only means that a equilibrium would be reached faster than a slow reaction. Increasing in temperature increases the rate of reaction. On the other hand, if a reaction is exothermic, the reverse reaction would be endothermic. Adding heat (by increase temperature) or remove heat would shift the equilibrium, which is studied in thermodynamics.
