Does raising the temperature of a reaction always make the reacetion progress more toward the products?

Answer 1

In the case of an exothermic reaction, taking heat away helps it progress towards products. Endothermic reactions are absorbing heat; therefore, adding heat moves it to product side.
This is just the shifting of equilibrium part.

Kinetics: Heat added, whether from the rxn exo or externally, speeds up the reaction. With industrial size batch exothermic reactions, one must constantly remove heat by cooling jackets or the reaction can get away from them.

Answer 2

Even with exothermic reactions, raising the temperature can cause the reaction to favor the reactants instead of the products.

Consider if a reaction is creating gaseous products from liquid reactants in a closed environment. Raising the temperature will raise the pressure and could even reverse the direction of the reaction.

Answer 3

Not necessarily. Exothermic reactions need cooling to take away the heat of reaction for the reaction to continue. The statement is true for endothermic reactions, where you need to supply heat for the reaction to continue.

Answer 4

It all depends which type of reaction are u talking about-wheather endothermic or exothermic.According to le-chitareals principal
1)endothermic reaction are proceded in forward direction on increasing temp.(products dominate)
2)exothermic reaction proced in backward direction on increasing temp.(reactants dominae)
